LSD (Lock / Shaman / Druid)
A control-attrition comp that got stronger as TBC went on. Elemental Shaman utility + double Fear + Cyclone create relentless control while DoTs grind the enemy out. Wins the long game against almost anyone.
Sustain
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.
