Starting here.

I'm gonna start playing here today. I was on Outland until they closed it down and I don't really care much for Wrath. I'm probably gonna go alliance. Are there any classes or roles that need to be filled? I usually play melee DPS or heals. I've never tanked before but it would be fun to learn with the right people.

I suggest you to choose a class which can do healing and dpsing so you have options :)

There's a severe lack of healers on the PvP scene if you want to do bgs and arenas.
