Straight to the point, we'll be attempting this tonight with 1 tank, 2 healers, 7 dps.

Tank - Blood DK
Healers- Disc Priest, Holy Paladin
Ranged - Spriest, Hunter, Lock, Moonkin, Ele Shaman
Melee - Rogue, Warrior

Would best kill order be: kaolan -> regail -> asani ?

And how should we manage the Corrupted Essence Stacks?
