Luv mmo's, but really not a fan of pvp. If a game lists pvp as one of it's primary drawing points I don't even go to their site. Don't mind there being set areas for pvp and may even do some pvp at times if there's a purpose to it.
Enjoyed the silliness of WoW's pvp, but it was a side thing, done once I had hit max lvl and was bored.
EVE's low sec, forced pvp eventually killed the game for me, admittedly after 3.5 years. :p
Age of Camelot had a decent pvp as taking the enemy castles gave an nice overall buff to everyone in your kingdom, involved in pvp or not. The negative was those castles were out in the middle of no man's land and once you got killed you respawned far from them, so you generally got 1 run at the castle and once you died the battle was over by the time you got back or you got ganked before you ever got back.
So not really a fan of pvp. Prefer a good storyline, especially if it has humor will keep me playing for a long time.
