3 comps
AWarlock / Resto Druid
The definitive sustain team of Season 2: an SL/SL Affliction Warlock and a Resto Druid who simply refuse to die. You don't burst anyone down — you blanket the enemy in rot, chain-Fear their healer into oblivion, and win the mana game every single time.
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.
BRet Paladin / Resto Druid
'Ret/Druid.' A sustain-and-control comp that wins by outlasting: the druid rolls HoTs and chains Cyclone/Roots/Bash while the Ret adds Repentance and a Hammer of Justice stun. Blessing of Sacrifice and Freedom keep the druid free, and layered CC on the enemy healer eventually forces the kill.
