I currently have two 85s, my Hunter and Death Knight. Both are already in full 378s (for the most part) and have 4T12. The thing is, I want to focus on just one so I can join a nice raiding guild instead of doing pugs all the time. I just can't decide on which I want to play.

Now before you go saying "Play which one you enjoy most!", that's just the problem. I enjoy both of them. Each time I go to play one, I'll start wanting to play the other after a while. Hence why I have both of them geared up. What I'm looking for is an outside opinion on which would probably be the better one for me.

Overall, the main things I do are DPS, run old content for fun/achievements/mounts, and PvP. I never really like to heal or tank. Tanking just gives me a headache, and I'm not much of the healer type. I like destroying my enemies.

I understand that Hunters aren't the best in PvP right now, and that's one reason I keep going back to my Death Knight. However, I realize that it can change at any point (namely the next expansion due to the removal of minimal range), and that I shouldn't base my choice on flavor of the month, so to speak.

So given that I only really wish to DPS, run old content, and PvP, which would probably be the best choice for me? I don't really mind melee or range all that much. I'm about equal on them, so that isn't a deciding factor for me.

Given the info provided I would say focus on your hunter.
