Subtlety Rogue
Rotation
Opener: Stealth, Ambush or Garrote, Hemorrhage to 5 points, Slice and Dice.
Priority: Hemorrhage as the builder (the party likes the debuff), Eviscerate or Rupture at 5, Slice and Dice up. Kidney Shot and Blind for control.
Cooldowns: Preparation resets Vanish, Sprint and Evasion; Ghostly Strike for dodge; Premeditation before an opener.
Forever notes: Subtlety is the PvP tree: openers, control and escapes. For dungeons it works; for raids pick Combat.
Stats
Agility and Crit for openers, Hit to 9%, Stamina for PvP survival, then attack power. A high top-end dagger for Ambush.
Subtlety is burst, so weapon damage range beats steady stats.
