AWMP (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.
BRetcleave (Warrior / Ret / Shaman)
Retcleave is TSG's controlling cousin: an Arms Warrior and a Ret Paladin train a target while a Resto Shaman sustains, but the paladin trades a second warrior for Repentance, Hammer of Justice, and Freedom. Less raw instant damage than double-warrior, far more healer lockdown and burst on demand. A high-floor cleave that actually sets up its kills.
C5s DPS Zerg
The all-in 5s archetype: four DPS (arms warrior, sub rogue, frost mage, SL/SL warlock) stacked behind a single discipline priest. You don't win the long game — you CC the enemy healer, dump every cooldown on one target, and delete them before your lone healer runs dry.
