Yay, I meant somthing like, "Backstab Rotation". Backstab can only be from behind, and Makes (afaik)good dmg. So, you hit Backstab and get aggro then other 2/3 has Backstab to hit and try to get aggro, something like Aggro Ping Pong, Wold be nice in a Movie but it's too difficult to make, I guess. It's like playing with a ball, 1 guy is in the middle and the others standing in a circle are throwing the ball to each other, the guy in the middle has to catch the Ball.

Sword (Middle tree (don't know the name in english now)) is imho the Best PvE tree. Because you don't do dmg only when your critting.

THen how will you manage him using sinister strike to use excess energy?
Hm I don't realy know, I'm not really the Rogue player. And don't take it too serious. Was just an Idea ^^ Efficiency? No one was talking about it
