Glyphs: Sinister Strike, Adrenaline Rush and Rupture

Stats: spell hit > agi > expertise > haste > white hit = mastery > crit
Glyps: tank&spank: Mutilate, Rupture and Vendetta
movement: Mutilate, Rupture and Backstab
Cycle: 4+ combo points, use finisher, keep up Rupture and use Envenom otherwise. Below 35% use Backstab instead of Mutilate.
Stats: agi > expertise > spell hit = haste > white hit > crit > mastery
Glyphs: Backstab, Eviscerate and choose the third between Shadowdance or Hemorrhage.
Cycle: Keep up Slice and Dice and Recuperate, also use Rupture once and use Eviscerate spam to keep it up. Use Backstab as your basic attack. Use Hemorrhage only to debuff if there is no feral druid or arms warrior.
Change crit to haste or hit. Take care to be spell hit capped. Assassination and Subtlety specs need to get expertise cap too. It is nice but not needed for Combat spec.
