3 comps
RMP (Rogue / Mage / Priest)
The iconic TBC 3s comp. Sap, Sheep, and Blind chain the enemy healer out of the game while the mage's Shatter combo and the rogue's stunlock delete a DPS. Pure setup, pure control, highest skill ceiling.
MLD (Mage / Lock / Druid)
A pure caster-control comp. Polymorph, Fear, and Cyclone layer into near-permanent lockdown while DoTs and Shatter combos kill. Dizzying to play and to play against — a control clinic when piloted well.
WMP (Warrior / Mage / Priest)
Trade RMP's rogue for a warrior: less CC on the kill target, more raw burst and healing pressure. Shatter + Mortal Strike stacks huge damage while Poly and Mana Burn lock the enemy healer.
