A5s Caster Cleave
The ranged-control 5s archetype: stacked casters (mage + lock + shadow priest) layering Poly, Fear, and Cyclone behind a healer core. Kites melee cleave and kills through control — high ceiling, high coordination.
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.
ARogue / Holy Paladin
Ride the tankiest healer in the bracket. The paladin's Freedom and Blessing of Protection keep the rogue glued to a target while the paladin simply refuses to die. Strong into cleaves, weaker into Mana Burn.
AWarlock / Holy Paladin
Fear control plus the tankiest healer alive. You almost never lose your healer, and DoT pressure eventually wins — but without Mana Burn your kills are slow, so patience is the whole game.
