Warlock / 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.
Control
WLD (Warrior / Lock / Druid)
Warrior/Lock pressure married to Druid mobility and Cyclone. Constant Mortal Strike + DoT damage while the druid kites and locks the enemy healer out with Cyclone. Strong cleave with real staying power.
