Shadow Priest or Warlock?

[Lantel]

Hey everyone got a few more questions heh.

ok so first I know theres alot of debate on this but I dont particularly like healing so I cant decide what I should be a shadow priest or warlock im pretty sure im gonna be a warlock just wondering what you guys opinions are.

If warlock whats a good spec I really like pvp so probably a spec that will increase my Damage Over Time (DOT) power.

Thanks in advance.
