Step 1) All ranged DPS is at max range, all melee dps is on his ass. Assign certain healers to certain zones. Must have >3 people outside of melee range at all times (in 10 man). Druid healers, Disc Priests, and Restoration Shaman benefit from the Shadow Crashes at least a little bit, so consider leaving them out if you need more bodies outside of his melee range.

Step 2) Get a range checker and set it to 15 yards. This is for Mark of the Faceless.

Step 3) Make sure people know the three rules of this fight. Rule 1) If you are Marked, MOVE. If you're near someone who is Marked, MOVE. Rule 2) Stop everything you're doing if you're anywhere near a person who is getting Shadow Crashed. Rule 3) Assign one or two interrupters for Searing Flames. Make sure their interrupt won't miss. Don't make it a ranged person unless you have to.

Step 4) Win. All caster DPS should wait for Shadow Crashes to DPS, as DPSing without them is the fastest way to go OOM ever and you're essentially doing thing in doing so. Shadow Crashes are 200% damage and haste at 25% mana cost. It's amazing.

Resto druids can cast Lifebloom from the pools to 3 stacks and then step out. The mana return on Lifebloom does work at full effect even though the heal does not when you cast it in a pool.

Disc Priests can cast PW:S from the pools with no reduced effect because it is not a heal.

Resto Shaman can cast Earth Shield from the pools with no reduced effect because the initial effect is not a heal. When charges are consumed, it will heal for less if you are in a pool. Healing Stream Totem follows this same rule--it's at 100% effectiveness only when the shaman is NOT in a Crash pool.

Step 5) If you're not winning, break the Vapors. It's the only way to regen mana. Remember to break one even if your healers are doing fine as forgetting will activate hard mode (Learned the hard way!). You heal 100 mana at the cost of 200 HP. Then 200 mana at the cost of 400. 400/800, 800/1600, etc. At 5-6 stacks, get out. You will die if you stay in too long. The damage is Shadow and semi-Resistable.

The fight is all about placement. Mark of the Faceless and Saronite Vapors should be the only sources of damage for anyone other than the tank (unless you're doing hard mode). Mark isn't too bad if you move quickly. You should mutually move away from one another whenever possible. Try to pick a direction to run as well (we use the wall at the back). If people are getting hit by Shadow Crash, it's a DPS loss, a loss of mana on the healers, and time lost healing the tank (who is taking huge hits non-stop by the way).

Oh, and as for the kiting? You don't have to... necessarily. If you pop a cooldown for it each time you should be OK. Our main tank is a DK so he just pops Icebound Fortitude each time he does it. The 50% damage reduction counteracts the 100% damage increase, so it's as if nothing happened. Not gonna work in 3.2, but it's still not too bad.
