Strategy
The Ignis encounter is an endurance fight with a soft enrage (not a timer) that makes up the complexity of the fight and affects all members of the raid.

Tanking
For all modes, you will need a Main Tank to kite Ignis, and either an off-tank or a very skilled kiting DPS (probably two or even three on 25 man). If you attempt to turn the Iron Constructs molten and destroy them, you'll probably prefer an off-tank because of the mitigation and large buffer of health compared to a DPS. However, if you are going to simply DPS him down immediately (you will need to average about 3500 dps on 10 man for all 5-7 DPS), you can get away with a player who is able to aggro, dodge, and CC the constructs (prot warriors, prot paladin, mages, hunters with a pet, warlocks with a voidwalker, or a druid). Also, the constructs can be snared into place so any kind of druid is the best option.
 * Choosing tanks

As the main tank, have a hunter misdirect the boss to you, or simply run up and get aggro on him immediately. You should choose and make known which direction or area of the room you're going to kite him so the rest of the raid knows where to position themselves. Some groups choose to strafe him left to right (either across the room, or length wise near the constructs), around the entire room, or around one half of the room; note that he should never be tanked in front of the water if you are going to be destroying the constructs, as scorch will be dispelled. However, this is the optimal location for tanking him to reduce damage on the tank, and keep everyone in the same position throughout the fight.
 * How to tank

The second way to tank him is to bring him to the direct center of the room. Have the tank turn him away from the raid and when he scorchs the ground, turn him to the left or right and keep the melee DPS where they are. Then, after then 2nd scorch run across the boss and tank him in the opposite direction so the 3rd scorch goes to the right or left and the melee DPS can stay where they are. After the 3rd scorch comes, the 1st one should be down by now and you go back to the starting point. If done right, no one should take any damage from contrucsts blowing up nor should they lose Heat stacks. The off tanks should be ready to taunt them to water when they go molten and get out of the way of them blowing up.

Naxxramas geared tanks (item levels 200 and 213) can take upwards of 25000-30000 damage per hit from Ignis' melee strikes. As the fight goes on, his melee strikes will gain an additional 20% damage from each Iron Construct that is active (eventually, if left unchecked, it will get to the point where you are one shotted). His scorch is a cone that will damage anyone he is facing, so your back should always be away from the raid. Flame Jets will throw you into the air briefly, but since you aren't a caster, your abilities should not become locked. After a scorch has landed on the ground around you, strafe out of it quickly to avoid taking damage and get your melee DPS into a safe spot as well. You should not aggro any constructs unless you wish to cause additional stress to your healers.
 * Main Tanking - what to look out for

For the first 15 seconds of the fight, DPS Ignis. He doesn't have a cleave, and scorch won't be fired until 12 seconds into the fight (and you can stand behind him safely). When the first Construct appears, grab aggro and begin moving away from it. The more constructs that are up, the faster they move so eventually they will outrun you if you don't do anything about it. Off-tanks should only take about 1-2k damage per swing, so the damage they deal is negligible, however, since this affects your healers, if you can do something about it you should (as a prot warrior, you can charge constructs and then run past them, or intervene to a close ally to get away from enemies). If you're kiting them and you're not a tank, CCing abilities are vital to your group's survival. Frost Nova, Frost Traps and pet tanks, Void Walkers and destruction warlocks' AOE stun, and druid roots and travel form are all possible solutions, however they tend to only be effective for a few minutes. If your group is going to be destroying the Constructs, make sure you have a healer that can either heal you through scorch, or you have good CCers that can keep the constructs in the flames of scorch long enough to heat it up (moonkins and mages are very handy for that).
 * Off-tanks and kiters

Healers
Healers need to be on the ball to keep the main tank healed because of the significant melee damage dealt by Ignis. Casters, particularly healers, should take care to stop casting before Ignis uses Flame Jets, otherwise they will be locked out of their spells for 8 seconds. All players should make sure to move out of Scorch areas. Random players will periodically be charged and placed in the Slag Pot attached to Ignis' stomach. Whichever player is charged should be healed through the DoT (they gain a debuff to help identify it on your raid frames). You should instruct your raid members to stack on you for AOE healing.

DPS
As a DPS, your job is to not stand in scorched areas, to call out when you are inside of the Slag Pot, and stand behind Ignis at all times (preferably stacked on your healers for AOE healing). Ranged DPS should be used to destroy Brittle Iron Constructs if your raid decides to kill the adds (only powerful abilities like Chaos Bolt, Frostfire Bolt, Fireball, Aimed Shot, and Starfire should be used to beat the 5000 minimum damage requirement). If you survive being stuck in the Slag Pot, you should use the haste buff as best you can (10-second duration) to fire off your slower, more powerful attacks. Since this fight is heavily reliant on DPS, every DPS member of the party should have a minimum of 3500 DPS (4000+ group average recommended) for the duration of the fight.
