Seems decent, I don't know why you decided to go Infiltrator though. The Assassin tree seems more viable, with a stun and blind.
this is my opinion. http://rift.zam.com/en/stc.html?t=0MMfp.0AMct0boz.Ghtoq00ub.V0xI
- for survival or http://rift.zam.com/en/stc.html?t=0MMfN.0AMct0boz.Ghtoq00ud.fGobz
- for pure ranged damage.
The Bestial Fury standing on a pedestal + those other random damage increasing abilities just make for a better overall spec.
