Guild Wars and WoW have the best PvP in terms of being successful. I used to be in a HoH guild in Guild Wars and well, in WoW I was more of a raider (PvE person). However, you have to do some PvP sometime in WoW or you miss out on a lot of gear. Play Guild Wars if you like team based/well balanced PvP. Play WoW if you like gear based PvP that PISSES YOU OFF!!!!11!!1
