I played WoW from beta up until a few months ago. 3 70's, a 68, 60, etc etc.. like a million mid-level alts. That game just wasn't good for me. But I played on Warsong, then Dark Iron (in the PA guild), then Garithos, then Mal'Ganis.
A guy in our guild got one someone's private server, said it was pretty fun, but I don't know much about how to do it.
