4 comps
SRogue / Mage (RM)
The purest glass cannon in 2v2. Rogue and mage layer more crowd control than any other pair and cash it in for a single, lethal Shatter-plus-stunlock burst window. When the opener lands the enemy is dead before they trinket; when it whiffs, you have no healer to bail you out.
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.
