You may not be that good at using him yet then.
At first I felt the way you do but I only stayed with this class because I loved everything about it I'm on a PvP server and I'm level 28 and am heavily involved with PvP and now I'm doing 100k+ Damage in every warzone and its getting better. I'm soloing two people at once in rare cases and killing them both, you just ahve to learn how to use him the best way for you its not something you can do by following what others say
Good luck
