in demonology warlock is by far easiest class to play at lvl 70 the only class that will give you probs is the stunn rgs and that is if they hit you first, to win get death call on em intercept with pet dot and life drain till they die, in many arenas have killed 2 rgs at same time while hunter partner was dead20/41 will own all classes in pvp if played right.  of course their are exceptions. if you can get out of stun lock rgs can be easily owned.  in destro spec you havent a chance against a rg, or at least i dont but in 20/41 you should own all.
