Blink could be better, Don't use arcane missiles that much, mostly fire. For Questing, they are pretty good. I've soloed mostly, have only needed to group for elite mobs. In PvP, I don't know if its me or what, but the only way I have a chance is if I get the jump on them or if i'm with other players. If I get hit without knowing, I'm pretty much dead after that.
