4 comps
SWarlock / Disc Priest
'Lockarena.' Double-Fear control makes the enemy team play in slow motion while UA and DoTs tick them down and Mana Burn/dispel keep you ahead. The highest control ceiling in 2s.
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.
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.
BRogue / Warlock
Rogue/Warlock is a double-DPS tunnel comp that wins by chaining control across every diminishing-returns bracket while the Warlock's dots bleed a pinned target out. There is no true burst here — outside a lucky Nightfall Shadow Bolt, you kill with relentless pressure, not a single global — so every kill is a CC chain you built by hand. Land the opener and the game is often decided in the first twenty seconds; whiff it and you reset and try again.
