I still enjoy playing on a PvP server, even as a protection specced warrior. Sure there's plenty of zergs, but that doesn't ruin the game. I enjoy PvP on the whole though, and I'm a fairly well geared lvl 60, so maybe I'm just biased. I've tried doing the massive PvP battles and it's just not as much fun (for a warrior) as small scale PvP. I like running around in a duo or solo in places like WPL. Corpse camping really hasn't bothered me. In the few times I've ever been corpse camped, I haven't been in a hurry. If I get back to my body and they are sitting and waiting for me, I generally go do something else for a little while - go to the bathroom, grab something to eat, check my e-mail... do something at least semi-productive and take a quick break from WoW while letting them waste their time.
