What's your favorite class for PvP?

[Edward]

Alright then, Some of you might know my name, but that's not the point.
What I'm here for now, is to ask a simple question.
Out of all of the classes, and combination's available to us on WoW.
What is your absolute favorite for PvP?
It doesn't have to be a class you play, either.
Personally, I love watching a good Destruction Warlock at work.
Something about three-shotting people is just so tasteful.
I also play a Destro Lock, which furthers my love for them.
So, GamerzPlanet.
Lets see your answers.

A good lock that knows what their doing can rape at pvp easily.

Either Mage or Warlock :)
