This new 5-player Heroic dungeon begins the quest to save all with a look at the desolate future of Azeroth, should its defenders fail to stop Deathwing.
This new 5-player Heroic dungeon sets the final stage by bringing players face-to-face with the Twilight’s Hammer in present-day Dragonblight, where Thrall and the Dragon Soul must be safely escorted to Wyrmrest Temple so that the assault on Deathwing can commence.
Players have the opportunity to take the fight to Wyrmrest Temple and beyond, assisting Thrall and the Dragon Aspects as they seek to bring an end to the Black Dragonflight once and for all. 10- and 25-person raids will get to take on Deathwing himself, with three levels of difficulty to consider and epic gear to claim.
Alizabal presents an all-new boss challenge to player in 10- and 25-player arrangements who control Tol Barad. This boss will be available with the start of Season 11, one week after the release of patch 4.3.
The most deadly and experienced rogues will play a central role in the fate of the world the rogue’s way: by manipulating key events from the shadows. Players will travel across continents to accomplish crucial missions of reconnaissance, burglary, infiltration and, of course, assassination. Rogues who succeed will receive a paired set of daggers that will become increasingly lethal as their bearer progresses along the legendary quest. At the height of their strength, they will be imbued with the vile essence of the Old Gods, as well as the maddened fury of the Black Dragonflight -- bestowing great power upon their bearer. These powers include a stacking increase to Agility which builds until dark wings unfurl from the rogue’s back, removing the combo point cost and increasing damage of finishing moves for a short time. In addition, the wings which can be spread on command (with no combat benefit) to slow a rapid descent, allowing the rogue to slowly fall to the ground… or enact a little death from above!
This new grouping feature allows players to quickly and easily form a pick-up raid for a specially tuned version of the current tier of endgame content: the Dragon Soul raid.
This new feature allows players to customize their gear like never before: copying the appearance of one magical item onto another.. You’ll find Transmogrification, Void Storage, and Reforging vendors in Cathedral Square, Stormwind and The Drag, Orgrimmar.
In addition to the bank, players will now have access to a new "deep storage" system, allowing characters to free bag space by setting aside coveted gear. You'll find Transmogrification, Void Storage, and Reforging vendors in Cathedral Square, Stormwind and The Drag, Orgrimmar.
The former Reforging vendors have been... retired. The ethereals have chosen to take over the business and joined their Transmogrification and Void Storage service providers. You'll find them in Cathedral Square, Stormwind and The Drag, Orgrimmar.
Make your way to Darkmoon Island during the first week of every month to take in the new Darkmoon Faire, complete with new quests, shows, games, recipes, toys, balloons, souvenirs, snacks, beverages, achievements, and titles.
The amount of experience needed to gain levels 71 through 80 has been reduced by approximately 33%.
Many Group quests in Outland and Northrend have been re-tuned to allow players to complete them solo. They are no longer labeled as Group quests.
Relevant questgivers have been moved into Outland and Northrend dungeons. The majority of dungeon quests for these zones are now available from within their respective dungeons.
Vengeance for Protection warriors, Protection paladins, Blood death knights, and Feral druids has been redesigned slightly. It no longer ramps up slowly at the beginning of a fight. Instead, the first melee attack taken by the tank generates Vengeance equal to 33% of the damage taken by that attack. In addition, as it updates periodically during the fight, it's always set to at least 33% of the damage taken by the tank in the last 2 seconds. It still climbs from that point at the rate it did previously, still decays when damage is not taken, and still cannot exceed a maximum based on the health and Stamina of the tank.
Threat generated by classes in active tanking modes has been increased to 500% damage done, up from 300%. This applies to druids in [Bear Form], death knights in [Blood Presence], warriors in [Defensive Stance], and paladins with [Righteous Fury] active.
Spells which have an effect broken by taking damage past a threshold ([Entangling Roots], [Fear], [Frost Nova], etc.) now count damage that was prevented by damage absorbs or other damage reducing effects.
Buffs
All raid and party buffs which grant group members 10% increased attack power have been changed slightly. They continue to provide 10% increased ranged attack power, but now provide 20% increased melee attack power.
[Abomination's Might]: The melee attack power bonus from this raid buff has been increased to 10/20%, up from 5/10%. The ranged attack power bonus remains 5/10%.
[Blessing of Might]: The melee attack power bonus from this raid buff has been increased to 20%, up from 10%. The ranged attack power bonus remains 10%.
[Trueshot Aura]: The melee attack power bonus from this raid buff has been increased to 20%, up from 10%. The ranged attack power bonus remains 10%.
[Unleashed Rage]: The melee attack power bonus from this raid buff has been increased to 10/20%, up from 5/10%. The ranged attack power bonus remains 5/10%.
Death Knights[]
[Death Strike] now heals the death knight whether or not the attack misses, or is dodged/parried. As a result of this change, Death Strike no longer refunds its rune cost if it fails to hit the target, as the death knight will still receive the healing effect.
[Blood Presence] now provides an armor bonus of 55%, up from 30%.
Death Knight pets now properly inherit their master’s crit and spell penetration stats.
Talent Specializations
Blood
[Blade Barrier] has been redesigned. It now passively reduces damage taken.
[Swipe] has been reduced to 340% weapon damage, down from 415%.
[Bear Form] now provides an armor bonus of 120% at all levels, up from 65% for characters below level 40, making it easier for lower level druids to tank dungeons.
[Bear Form] now provides a Stamina bonus of 20%, up from 10%.
Talent Specializations
Balance
[Fungal Growth] now displays an alternate spell effect when viewed by players hostile to the druid.
The casting bar for [Tame Beast] should now always indicate the correct cast duration at high values of haste.
Mages[]
[Pyroblast]’s initial damage has been increased by approximately 26%, and its damage over time has been increased by approximately 100%.
[Fireball] damage has been increased by approximately 17%.
Talent Specializations
Fire
[Living Bomb] damage over time has been increased by approximately 10%, and explosion damage has been increased by approximately 120%.
[Combustion]’s damage over time can now hit critically.
Glyphs
Mages who apply both [Glyph of the Monkey] and [Glyph of the Penguin] at the same time will cause the polymorphed target to be randomly transformed into one of the two forms.
Bug Fixes
Living Bomb’s interaction with [Impact] has been cleaned up, and should no longer sometimes fail to spread Living Bomb to new targets. We hope.
Combustion will now scale correctly with Living Bomb, Pyroblast and [Frostfire Bolt], resulting in an increase in Combustion damage.
Portal spells should now all have the same mana cost.
Paladins[]
[Holy Radiance] now has a 3.0-second cast time, no cooldown, and requires a player target. That target is imbued with Holy Radiance, which heals them and all group members within 10 yards instantly, and continues to heal them by a smaller amount every 1 second for 3 seconds.
[Judgment] no longer automatically targets a nearby enemy when the player attempts to activate it without a hostile target selected.
[Seal of Insight], when Judged, no longer returns 15% base mana to the paladin. Judging Seal of Insight still causes damage, and melee attacks will still restore 4% of base mana.
[Seal of Truth], when Judged, now benefits from a multiplier of 20% per stack of Censure, up from 10%.
[Atonement] will now account for the target enemy's combat reach when calculating proper range, enabling it to be used on large creatures such as Ragnaros and Ala'kir[sic].
[Spirit of Redemption] has been rebuilt to address a few functionality issues and make it more responsive. Spirit of Redemption otherwise remains unchanged.
[State of Mind] has been redesigned and is now called [Heavenly Voice]. Heavenly Voice increases the healing done by [Divine Hymn] by 50/100%, and reduces the cooldown of Divine Hymn by 2.5/5 minutes.
[Guardian Spirit]’s healing bonus has been increased to 60%, up from 40%.
Fire Elemental now benefits from 55% of its master’s spell power, up from 50%
Enhancement
[Improved Lava Lash] now causes [Lava Lash] to spread a [Flame Shock] debuff from the target to up to 4 nearby targets. This excludes crowd-controlled targets and those who already have a Flame Shock debuff from the shaman.
[Improved Lava Lash] no longer increases base [Lava Lash] damage by 15/30%. This increase has been rolled into the base Lava Lash skill.
[Mental Quickness] has been redesigned. Instead of granting the shaman spell power, Mental Quickness now causes Enhancement shaman spells to behave as though the shaman has spell power equal to 55% of attack power. Enhancement shaman spells no longer benefit from spell power from other sources.
[Ancestral Healing] now also causes the shaman's heals to increase the target's maximum health by 5/10% of the amount healed, up to a maximum of 10% of the target's maximum health, for 15 seconds. This effect does not stack if multiple Restoration shaman are present, and does not apply to heals from procs.
[Riptide]'s periodic healing coefficient has been increased by 50%. The initial direct heal is unchanged.
Bug Fixes
[Chain Heal] will now animate properly when it bounces to the shaman.
Fixed a bug that caused Doomguard and Infernal to benefit dramatically more than intended from Demonology Mastery.
Warriors[]
[Charge] (and related abilities) should now correctly path to a target even if the target moves during the Charge. This change should decrease the likelihood of the warrior Charging to a different location than the target.
Players who use Dungeon Finder for a random Heroic dungeon will no longer be locked to that instance. Previously, players who entered an instance via the Random Dungeon option were then prohibited from queuing for that dungeon or entering the instance manually via the portal. Players should now always be able to complete a specific Heroic dungeon once per day regardless of any random dungeons completed.
Players now only have to kill two of the four Troll avatars before they may face Hex Lord Malacrass.
Guilds[]
Guild Standards are again useable in Firelands. Duration has been increased to 15 minutes, the effect has a 100 yard radius, and now affects dead players.
Inactive Guild Leader Replacement
Guilds with inactive guild leaders can now usurp the leader under specific conditions.
The gnome racial [Escape Artist] now has a spell animation associated with its effect.

Bag Search
A search field has been added to allow players to search bag, bank, guild bank, and Void Storage inventories for specific items.
The Reforging interface has been updated and improved.
Quest Tracking areas or points of interest will now show on the mini-map, in addition to the World Map.

Added new rotation, zoom, and pan controls are now available in all windows with player models in UI frames.
Players can now unlearn profession specialization without unlearning the profession (Engineering & Alchemy).

General Bug Fixes[]
[China, Korea, Taiwan] Pasting from the clipboard should no longer cause the client to crash.
Many tooltips have been made more accurate.
Using #showtooltip in a macro should now cause the action bar icon to become highlight at the appropriate times.
Pet bars will no longer sometimes disappear when zoning.

Reflected spells are now affected by the resilience of the player that ultimately takes damage.
The process of re-integrating mages into Night Elf society has advanced such that Night Elf Mages now receive all racial bonuses, specifically Elusiveness.
Secondary debuffs will now more reliably apply to targets which are knocked out of Stealth or Invisibility.
Trivia[]
Patch 4.3 is the longest patch cycle between content releases in WoW history, lasting over ten months. 4.3 lasted, with few minor bug fix patches, from November 2011 until Mists of Pandaria was released in September of 2012. This extremely long dry streak had players very unsure of what Mists had to offer. This led to Blizzard releasing patches is a much faster fashion in MoP with a patch every 2-3 months and every other patch containing a raid.
Patch 4.3.0
[Master of Alterac Valley] no longer requires the Alterac Valley Blitz[sic] achievement.
[Tol Barad Veteran] now requires 25 victories in Tol Barad, down from 100.
[Bear Form], death knights in 
[Blood Presence], warriors in
