Join the OcUK hordies on Shattered Halls !
if that's really not an option I'd suggest pally, there's lots of locks around and all you can do is DPS - with a pally you can heal or tank depending how you spec, and so you'll always be in demand (and that's coming from a lvl 70 lock who's got bored with his toon)
ooooooh i just installing wow, a little late i knowhow do i join this ocuk thingy ??
