You really shouldnt post three messages at the same time it's against the rules and saying owning range with death grip isn't completly mages freze you to the ground and then use blink, hunters jump awey, warlocks use their shadow portal thingy, priests use fear and run while they have the chanse, shamans use Hex and Bomkins use waterwave to push you awey. And those are just some of the ways to do it, the problem with people is that they belive that death knights are beter in pvp the truth is that they are just simpler to play, the trick is to know what your enemy is going to do before he does it. If you for example take a look at the 3 vs 3 arena championship at BlizzCon few where playing death knights.
