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.
BFeral Druid / Rogue
A double-stealth burst comp that wins by never letting the enemy out of a stun. Both players open from the shadows and overlap stuns to delete a target inside one window, before a healer can react. It is one of the highest-skill, most gear-hungry double-DPS comps in the bracket — all ceiling, little forgiveness.
BRogue / Warlock
Rogue/Warlock is a double-DPS tunnel comp that wins by chaining control across every diminishing-returns bracket while the Warlock's dots bleed a pinned target out. There is no true burst here — outside a lucky Nightfall Shadow Bolt, you kill with relentless pressure, not a single global — so every kill is a CC chain you built by hand. Land the opener and the game is often decided in the first twenty seconds; whiff it and you reset and try again.
C5s DPS Zerg
The all-in 5s archetype: four DPS (arms warrior, sub rogue, frost mage, SL/SL warlock) stacked behind a single discipline priest. You don't win the long game — you CC the enemy healer, dump every cooldown on one target, and delete them before your lone healer runs dry.
