Like Shintar, I don't really understand the sheer vitriol directed at this game. Personally, I rather like The Old Republic. It does have its flaws, and I can understand people who chose to drop their subscription, but I don't really see anything in the game that deserves this continuing hate.
It's like the level of hate reserved for a really nasty divorce, or a cheating spouse. To me, the venom reeks of "betrayal", and that seems excessive for a video game. I wonder if a lot of the haters were really invested in the game before it came out, maybe to the point of burning their bridges in their previous game. Then when The Old Republic turned out to be human after all, they turned on it.
Another possibility is that the haters think that the MMO audience is zero-sum. That every subscriber for one game must be stolen from another game. Thus by attacking an MMO that has both a significant number of players, and yet seems weak, they can bleed off players to boost their game of choice. In particular, the Guild Wars 2 boosters seem to exhibit a lot of this behavior.
Ironically, the people now in love with Guild Wars 2 seem to falling into the same trap. If Guild Wars 2 proves mortal, unable to stay atop the pedestal, will history repeat itself?
