Honestly, I do not hate the guy. I do not know him, so it would be ignorant for me to say that I hate someone without ever meeting him. For all I know I may actually like him on a personal level, and I actually wish him well in his future endeavors.
However, this does not mean that I share his vision of game design at all. I am happy that he is leaving wow because I do not share his (or his design team) vision of wow. And judging from the sharp subscription drop over the past year, I am not alone in my convictions.
Anyways, either side that you are on post what you think.
