You can now form same-faction raids with Real ID friends, allowing you to enter Raid Finder in groups larger than 5, run older normal or heroic raids, or participate in Battlegrounds. You will not yet be able to run normal or heroic Dragon Soul with cross-realm raids of Real ID friends.
Several typo fixes and clarified descriptions have been added to the Dungeon Journal entries for Dragon Soul.
Players no longer benefit from a role-based need bonus on the second of multiple copies of the same item on a single Raid Finder boss kill. For example, a player who chooses Need on two set piece tokens or two weapons (and wins the first) will only automatically roll 1-100 for the second from that particular boss.
Burning Tendons health has been reduced by 15% in 10- and 25-player Heroic mode. This change eases the burst damage requirement to complete the encounter, which should allow players to make use of more varied raid compositions.
The Priest spell Leap of Faith is no longer usable while under the effect of Carrying Winds.
[Vial of Shadows] damage (Lightning Strike) has been reduced to approximately one-third of previous damage. However, it will now trigger approximately 3 times as often. This is intended to keep overall DPS the same while reducing burst damage, especially in PvP.
