I'm an average player with average stats at best. I made my warlock after my Hunter, which was actually my first character for a while and hence, my first pvp experience which I tended to avoid as I was God awful at it and I didn't enjoy it at the time (Oh the irony.) I can confidently say if I made a new Hunter I could easily maintain a 2 K/d on it. They're not as utilitarian, I won't lie, but it's definitely not hard to use them.
