Well, this should be the final extension, with maybe a "christmas present" extension as well if updates don't help. They have made it quite clear the game will not be charged to play until it is in proper working order..aka FUN.
They won't charge people for the game until there is more to do than "log in, kill daily mobs, grind, and log out." They aren't Activision-B, although many people seem to believe so. I mean think about it..they've decided to forgo over 2 million dollars in pure profits just to keep their customers happy. You will never see Activision-B do that.
