remember to take into count about 6.0 changes off healing is being changed, You would need healer/dpsx3 tank. you could go shadow though.

the 5th place i would use a hunter it can fill missing buffs kinda well. As for the 2 priests maybe a shammy be a good move?


i would go

Druid tank or deathkight
Priest/lock ( the lock would not give you a 2nd healer choice)
Shammy (would probs make this the healer)
Mage
hunter
