I know it's been talked about before, but I've noticed blizzard really only responds to joke/fun threads with a comic one-liner or to answer very basic questions by new players (saw one a second ago that asked if they could realm/faction change at same time, worthy of a blue post?).
I know many posts are volatile and overly-critical on the forums, but even many of the constructively critical posts, even those that get on the popular threads list never receive any blue response. I'm just tired of useless blizz posts that at most just give the illusion of being involved in community discussion.
