3 comps
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.
BHunter / Disc Priest
Hunter/Disc Priest is a patient attrition comp that wins by strangling the enemy healer's mana rather than out-bursting the lobby. The hunter kites at range chipping away with Viper Sting while the priest layers Mana Burn, and when the enemy pool runs dry a single Bestial Wrath window ends the game. It is a control comp that rewards discipline, map awareness, and knowing exactly when to commit your cooldowns.
BPHP (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.
