I'm the opposite. I hate PVP in MMOs. If I want PVP, I'll go play an FPS, I don't want a bunch of level 60 losers ganking everyone in zone where level 20 players are trying to level up.
But, now your a carebear because you dislike something people with low esteem like to do! PvP in theory is quite fun, in practice not so much. A few game with HUGE battles (DAoC, Warhammer) had some pretty good PvP as it was push and pull, seldom did a side dominate all the time. But most PVP want to win all the time and as soon as they loss a few times "games unbalanced", "PvP is broke" etc... NO pure PvP MMORPG has lasted, there is a reason for this, some have got it wrong, but a few where not to bad. its simple, in a true no holds bared PvP you have 5 guys who win and 95 who lose, those 95 get bored, game dies. Arena's are True PVP but most PvP's dont like um, even footing, fair fight and all..
just an opinion of course.
