4 comps
S5s Triple-Healer Control
The definitive S2 immortality comp — three healers behind an Arms warrior and Affliction warlock who never stop applying pressure. You don't out-burst anyone; you refuse to die and grind the enemy team into an empty mana bar. Every game is a war of attrition you were built to win.
A5s Melee Cleave
The default competitive 5s archetype: stacked melee burst (warrior + rogue) behind two or three healers. 5s in TBC is less rigid than 2s/3s — think in team archetypes, and melee cleave is the highest-floor one.
B5s Double-Healer Control
The attrition archetype: a healer-heavy core with a warrior + mage for pressure and CC. You almost never lose a teammate first and grind the enemy out — but you need a real kill condition to close, not just survive.
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.
