MMMMP vs LLLLP For PvP?

[vincenntxue]

I know I could farm dungeons with both, mages being a little trickier but possibly faster? Locks seems a bit slower to kill but safer/easier, though the pets don't always hold aggro for bosses, but at least halfway through. PVP I'm not sure as I haven't had a chance to try both, but I'd definitely want to be closer to top dps in bgs when they come out (assuming follow is allowed) and here's where I'm confused on which to choose.

Warlock
Easy DoTs, don't need to face target and can literally run around/cast, plus it synergies with my priest more.

Mage
Crazy 1 shot bursts or pretty close, but have to be facing the target when casting. Nova/blink could work for all casters very easily, and frost spec synergies so well with each other.

So basically, if I'm looking for top DPS numbers AND KILLS, would 4locks or 4mages be my go to?

I've adjusted the title of the thread so that it isn't huge and doesn't get cut off.
Please keep the titles of threads concise and to the point.
