It's the game as a whole that is the problem which isn't exclusive to PvP. They treat all of the content outside of the MSQ as a sideshow, lots of potential, all of it wasted. Islands, PvP, Criterion dungeons, Relics, you name it, they've dropped the ball on it, and rather than pick that ball up they'd rather just kick it down the street for future expansions to maybe pick up again. As long as the MSQ doesn't suck and the games selling this is the forseeable future for all content.
