My comp has remained and won't be changing for MoP.

DK blood tank
WAR arms
Hunter BM
Hunter MM
Shaman resto

I have my hunters bounce a follow and leap backwards off the tank so they always face the intended target. Tank chooses targets unless I give him one. I open with an AE band of D&D and Explosive Trap x2. Send melee in with misdirects and then switch from single target dumps to multi target dumps. I do that by disabling and enabling keymaps with isboxer on the fly.

So instead of this dump:

/cast Outbreak
/cast Slam
/cast Arcane Shot

I do this one:

/cast Outbreak
/cast Whirlwind
/cast Multi-shot


I find it to be pretty good. I've beaten the heroic end time runs and done some of them with pretty good measure. The only fight that ever gave me fits was baine and to a smaller extent Sylvannas. MoP will most likely have fights like that but we'll see.
