I've been top of the damage boards with my merc since level 14 and I love pvp. I've faced off 1v1 many times with levels 30-40+ and have won quite a few times. I think it's way fun and I'm having a blast. It's pretty fair from my point of view at least!
From what I've heard from level 50 pvp - just take out expertise. Should solve most problems. I'll probably be flamed for this, lol, but I don't intend to visit this thread after this post. Have at it, trolls!
