Recently I went to a gaming meetup (game makers not players lulz) and they talked about guys like this. They're called whales. Not cause they're overweight but because they spend shit-tons of money on games. They're the first ones to complain about shit. They'll say a change is retarded and threaten to stop playing. Next thing you know they're participating like nothing happened, spending even more monies.
This guy complaining just means blizzards done something right. They built titles that could hook people and make them emotional about it.
Either that or dis guy is fuked lulz
