From the front page Dev talk interview feedback:
"So disappointing. Waste of my time."
"We were promised a decent Q/A with new info. You answered none of our questions."
But when there was a fullblown Q/A for WOD, people complained that stuff never go in, so:
"we made the mistake with Warlords of talking about too much too early, and some stuff didn't make it."
So Blizz is tightlipped as not to spill any secrets about things that MAY NOT come in the expansion and people are crying. CHRIST.... you guys whine more than my wife, on her period.
