Hey guys

I have a rogue and a priest at 85, im trying to decide which to level to 90 and play.

My problem with priests was i prefer to kill rather than heal as i found playing 85 disc. So i think ill want to be shadow spec.

So will shadow priest be a decent choice for MoP? Or are there issues etc, I wont want to invest time and find ive got a terrible class to deal with

Im looking at a 90% pvp point of view, i never really pve.

Thanks Guys!
