Rogue / 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.
Sustain
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.
