I'm getting ready to roll with a guild on the new PvP server, and I have no illusions about what I'm getting into. I usually play as a carebear farmer, but I've played on pvp servers before, and I expect this one to be much more pvp-ish than before. But I know what I'm getting into, it's fine. I'll be running from graveyards a lot and getting roflstomped by people with gear and skill and a thirst for tauren blood, and that's just fine.
As a previous poster said, I'll take the dangerous, vibrant world over the safe, sterile one. To Xibalba!
