As for the Assembly of Iron, this is a three phase fight and the order you choose to kill each of these bosses changes the way the fight progresses. That's due to their Supercharge ability. I've personally only done this fight killing either Runemaster Molgeim or Stormcaller Brundir last, I haven't attempted Steelbreaker last yet. Keep in mind that as each one of the Assembly dies, the other two reset to full health, so it makes no sense to split DPS on this fight, all DPS should be on the kill target.

As a tank, warriors are very well suited to tanking Stormcaller Brundir due to our having a ranged silence (Heroic Throw with Gag Order) if talented for it as well as Shield Bash to interrupt his spell casting and Spell Reflect for those Chain Lightnings that get past the bash. If you're tanking Brundir after either Steelbreaker or Molgeim have died (whichever one you're killing first) then you'll want to save your Shield Bashes for Lightning Whirl. Once Brundir is the last to die, he begins periodically casting Lightning Tendrils on himself - during this period of time he is neither tauntable nor stunnable, so save any such abilities for when he comes out of it. Also, while Brundir can be stunned while casting Overload, he cannot be interrupted, so save Conq or Shockwave for those moments. My guild has me stand in for Overload when I'm tanking and just heals/cooldowns me through it, other guilds may deal with it differently. A warrior tank could easily run out and then charge back in if that was the strategy.

Tanking Steelbreaker is all about not letting him kill you. Don't let him stand in Molgeim's Rune of Power and try and kite him just far enough so that your melee can stand in it. Save your cooldown abilities for Fusion Punch if at all possible. You'll be constantly stopping and starting to kite him around. Some raids use three tanks on this fight so that each boss gets his own tank and some use two so that one tank ends up with both Molgeim and Steelbreaker on him (especially in 10 man, it can be very hard to bring three tanks to this encounter and still have the DPS to do it) - this can make for a very difficult kite. If Steelbreaker is not the first to die, his first Supercharge will only increase the amount of damage he deals and his second one (if he is the last kill target) will kill the tank in 30 seconds. This means that even with two tanks available, killing Steelbreaker last is a test in pure, unadulterated massive raid DPS, since you have at most a minute to kill him before you run out of tanks. (Obviously, if you have 3 tanks, you'll have an extra 30 seconds, but in 10 that's very unlikely and in 25 it's not really that much DPS time.)

Finally, tanking Molgeim is made complicated by his Runic Barrier, which reduces damage taken by 50% and inflicts 2000 arcane damage back on people attacking him. I believe it can be purged, dispelled and spellstolen (I'm fairly sure I've shield slammed it off, but not 100% as the fight is ridiculously hectic) and it should be as soon as it goes up, it can kill DPS who aren't careful. He also throws Runes of Power around that the DPS should take advantage of while the tank moves away from them. After the first Supercharge, he casts Rune of Death, which is a great big green circle on the ground that no one should stand in. What a unique and innovative mechanic for World of Warcraft, really, a lesson in the deadliness of floors. Man, my four years of playing this game (five, almost) have instilled in me a terror of the floor that borders on madness. Each step I take fills me with dread that at any moment a void zone or swirling purple cloud or big green aura will pop into existence and I'll have to run for it.

Anyway, yeah, Rune of Death, it'll kill you, don't stand in it. Finally, on his second supercharge Molgeim will throw down a Rune of Summoning and annoying lightning elementals will spawn, target a random player, and run over to give her or him a great big exploding hug. The elementals can be snared and rooted so piercing howl can be of use here if you have it and aren't the target (if you are the target you don't want to be anywhere near there) and hopefully the ranged DPS will AoE them down before aforementioned spiky, spiky hugs of death.

As a DPS? Don't stand in things, unless they're Runes of Power, in which case go ahead and stand in them. Do not stand in Runes of Death. Do not stand near Brundir when he's casting Overload. Pummel or stun Brundir while he casts Chain Lightning or Lightning Whirl. Run away from Lightning Tendrils. DPS Steelbreaker as hard as you can. It's all fairly basic, but please, please, please don't stand in Rune of Death. People will make fun of you.

Next week, hopefully, Warrior Q&A. If not, the Keepers of Ulduar.
