5s Shadowplay Plus
Shadowplay Plus takes the shadow priest and elemental shaman core and bolts on a frost mage, destruction warlock and holy paladin for a five-caster wall of ranged burst. It kills through raw instant damage stacked into one global, backed by a silence chain no single healer survives. When the burst is peeled, it simply mana-burns the enemy healer into the floor instead.
5s 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.
