The problem with MMOs nowadays are those type of players.
The expectations of a pristine, bug free, perfectly balanced, game that launches with absolute unlimited end game content where everyone can get gear in a 2 days.
And when it's not that, it's "THIS GAME SUCKS, FAILZ, *SUCH AND SUCH* IS A WAY BETTER GAME, I QUIT."
THEY are what's ruining MMOs.
