Shadow shot is worthless IMHO.

There has been a change so that Shadow Shot is auto targeted like the other skills, but it doesn't do enough damage to be worth considering. Yes, it does some AoE damage, but it is only worthwhile if it crits, otherwise, it's not worth the skill points. You would be better off putting the points into a passive (like DEX).

Honestly, next time I respec, I will be using Razor again. I went with Shadow for this expansion, and am seriously regretting it. The damage it does to mobs in Kraken Isles is negligible at best, and if that is the difference between life and death....well, it was nice knowing you.
