Despite what people will tell you, the leveling experience is not that much different between the server types. OK, so you get ganked by a 60 a few times on the way to level 60 yourself. What is that, maybe an extra hour spent running back to your corpse over the 150 hours or so it takes to get to 60?
And once you’re at 60, you can world pvp on either type of server. It’s not hard to initiate it on pve servers.
