WMP (Warrior / Mage / Priest)
Trade RMP's rogue for a warrior: less CC on the kill target, more raw burst and healing pressure. Shatter + Mortal Strike stacks huge damage while Poly and Mana Burn lock the enemy healer.
Burst
PHP (Paladin / Hunter / Priest)
A burst-and-control 3s: Ret + Hunter stack a big damage window while the priest and hunter traps lock the enemy healer. Freedom keeps the Ret on target. Strong burst, beatable by patient control.
