2 comps
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.
