After a couple of months of struggling with motivation to play wow, I am now leaning towards quitting and have in advance cancelled my subscription. Now I would need YOUR help in looking for another MMO in purpose of playing PvP mainly. So throw out your opinion about the best MMO for PvP!
Rift seemt intresting, but i'm worried about the significant similarity with wow, has this been an problem for anyone?
Guild Wars has some pretty decent PvP. Arguably the best you can find in this kind of game.
Warhammer Online was fun too, but it's a desert now.
You can try Heroes of Newerth/League of Legends/Bloodline Champions/Darkspore too (the last is still in beta though). They're not MMO's but they have some RPG elements and some nice PvP.
