3 comps
AFrost Mage / Disc Priest
The anti-melee comp. A Frost Mage kites warriors and rogues into oblivion while Polymorph and Mana Burn dismantle healer teams. Shatter burst finishes anyone who gets caught in a Nova.
BMage / Holy Paladin
Mage/Holy Paladin is the patient control comp of the 2s bracket: two of the best CC toolkits in the game stapled to the strongest single-target healer. You rarely burst anyone down — instead you kite, Polymorph, and Mana Burn until the enemy healer is out of gas, then delete their partner in one frozen window. It is a grind, not a race.
BMage / Resto Druid
A pure control comp: the Frost Mage builds crowd-control chains while the Resto Druid HoTs through everything and drops Cyclones to fill the gaps. You don't out-damage anyone — you out-CC them, opening a window where the Water Elemental and a Nova'd target simply cannot be saved. Every game is a puzzle of Polymorph, Cyclone, and roots.
