5s 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.
Cleave
TSG (Warrior / Warrior / Shaman)
'Double warrior.' The TBC stand-in for melee cleave: two warriors train a target with instant Mortal Strike pressure while a Resto Shaman keeps them up. Ignores CC setups, gets kited by casters. High floor, capped ceiling.
