Amazing raid dps. much better than any combat or sublety ive seen.

In this build the reasons for most of the talents i including and excluded are self explanatory. The reason i put that one point in quickening instead of Deadened nerves or Murderous intent was because well... you dont use backstab and i think 8% speed increase and 10% healing is alittle better than 3% reduced damage. you shouldnt be taking too much damage in the first place and you get healed for more than the damage dealt so 10% is a little better. Nightstalker isnt one the the really NEEDED talents but its worth it for the 30% damage increase to Mutilate and Garrote. I only put 2 points in precision just because all the new gear is going to have stats high enough to have you at the hit cap.
The rotation is simple. From stealth start with a garrote then slice and dice which will only be acouple seconds but enough to throw in 1 mutilate and a envenom to return SnD back to 26 seconds from the glyph. mutilate to 5 points and expose armor since it returns your combo points. then spend the 5 on a rupture and mutilate to 3-5 points and envenom. after that first cycle just mutilate to 3-5 points and envenom. keep doing this until rupture and expose armor wear off then get 5 points and do them both again. always do expose armor FIRST since its a free spell. This is one of the easiest rotations out there and pulls a great deal of dps. at level 78 i was pulling 3.4k dps on bosses having greens and blues for gear. with the new gear you should be the top dps in all raids on bosses.
