TBH I couldn't care less about PvP. Sure if it's there I might give it a try, in WoW I do the holiday BG achieves and I LOVED Hutt Ball in Swtor...
But if the word came down from On High that tomorrow "WoW 2.0" or any other AAA Mmo title was coming out and would have ZERO PvP, 100% focus on PvE, raids, dungeons, exploration and achievements, I would play that in SECONDS over a game that was 100% focused on PvP... Hell even 50% focused, as I would know that the 100% focused Devs would have more time/money/effort to focus on the parts of the game that I play.
