Mobius is tiny compared to the whole playerbase (or this game is in serious trouble). And as has been pointed out in this thread, the average "lifetime" of a PvE player in a game is about two years. Compared to a much, much longer lifetime of a PvP player. By the time everyone in Mobius is bored to tears of PvE in this game, we'll still be around fragging each other and having a blast. And buying paintjobs.
Well - unless they make it totally unfun to do that.
Ideally I'd like to see them do rich content for both the PvP and PvE crowd, since many of use do both, myself included. So your attitude of "PvE good, PvP bad" is kinda weird, especially since you keep on insisting they shouldn't change the base design of the game. Well, that includes Open mode with unrestricted PvP. So which one is it? Can't have it both ways.
