Lol I've got all of wotlk on my dks as far as experience goes I'm probably the single best dk player on my realm azgalor, tho I don't raid anymore and that's what people use to judge skill these days.

My 5s team is horrid atm, I have no real rating atm as I'm only just stepping in to arena this season and I'm vastly undergeared. But I do know dk theory quite a bit lol

Play on azgalor server horde side
