Go play cw/dc in pvp - do me a favour. Or do you think that dcs are so very useful in pve? And they said they are going to nerf cws. Can you stop screaming like little girls now?
Don't know either Ice Knife is a dot or they have more bugs that they're aware of. Btw what to expect in the future for CW: Will I be able to solo epics like rogues? Yes, Please! /sarcasm
I have a suggestion about Electric Shot - make it proc the effects of Split the Sky. This will give some nice synergy to paragon path and make both these skills useful (better damage and some control).
