Wow has the potential to do something I have not seen in the other MMOs I have played and quit. Lose a lot of people really fast. The community and social aspect of WoW is bad and getting worse. I left EQ, FFXI, Lotro because I just didn't want to play that game anymore. There was and still is no hate for those games. I left wow for 8 months and come back to a WoW that just isn't fun at all anymore. I find the game fun but if I wanted to play a single player game I would just play a single player game.
It may not be obvious but it only takes a handful of subscriptions to keep an MMO going and in the end could be a good thing for WoW. If in 5 or 6 years all that is left is 500k-1million of the true fans of wow there is a chance the game would actually be fun for me again.
The amount of stuff Blizzard is charging a lot of money for now makes me think the old Blizzard is gone for good. All we seem to have now is a company that wants money and will do anything to get it.
