BBeastcleave / KFC (Warrior / Hunter / Paladin)
KFC is TBC's iconic melee cleave: an Arms warrior and a Beast Mastery hunter share two overlapping healing debuffs and dump every cooldown on one target while a Holy Paladin keeps them topped. It wins by making a kill target un-healable, then bursting it down inside a stun. The moment it gets kited and controlled instead of getting to press, it falls apart.
BWarrior / Resto Shaman
Horde cleave at its most direct: Windfury Totem and Bloodlust turn the arms warrior's Mortal Strike into an instant-kill window while a Resto Shaman refuses to die behind Earth Shield and totems. Purge strips the enemy healer bare between swaps. It trains and swaps rather than kites, so control comps that lock the shaman down are the entire problem to solve.
BWarrior Cleave (Arms / Fury / Paladin)
Two warriors, one Mortal Strike debuff that never falls off, and the sturdiest healer in the game standing behind them. Warrior Cleave doesn't out-think anyone — it picks a target, glues both swords to it, and dares the enemy healer to keep up through 50% healing reduction and relentless snares. When the swap lands and the cooldowns pop, people simply die between globals.
