Beast Mastery Hunter
Rotation
Opener: Hunter's Mark, send the pet, Aspect of the Hawk, Serpent Sting, Aimed Shot, Multi-Shot, then auto-shot weaving.
Priority: Never clip auto-shot: Aimed Shot and Multi-Shot only when the next auto is 1.5 s away; Arcane Shot as a filler at close range; Serpent Sting on long fights. Pet on Growl-off, Claw or Bite on cooldown.
Cooldowns: Bestial Wrath + Rapid Fire together; Intimidation for pet threat; Feign Death when you pass the tank.
Forever notes: The Nov 2 notes doubled Aimed Shot's bonus, raised Arcane Shot and Serpent Sting, and buffed Aspect of the Hawk; the Nov 3 hotfix put those numbers live. Hunters are stronger than Classic at every level.
Stats
Agility (attack power and crit), Hit to 9%, Crit, then Intellect (Careful Aim if you took it) and Stamina for the pet-swap moments.
Pet talents matter as much as yours; keep the pet at your level and fed.
