Accepted wisdom has it that whenever an MMO is granted a major expansion, add-on or upgrade, the existing subscriber base will become instantly polarised and a vast majority will turn their noses up in disgust at how the development team has single-handedly decimated their entire reason for living - the game into which they've poured so much time, love, effort and (most importantly) subscription fees. Player numbers inevitably dwindle, game servers become akin to deserted wastelands and the companies in charge start firing off press releases left, right and centre about how wonderful the game is, how steady the user growth figures are and whether you'd like to take advantage of its special 14-day free 'comeback' trial offers.
