They're being honest and giving us an insight into their development cycle. Sometimes, things would come at the cost of a raid tier, but the fact that the community continues to thrive on that as a joke, as a means to show Blizzard is a bad company goes to show how immature the community really is.
I'm studying to become a Game Developer, it's always been a passion of mine, but sometimes the community makes me feel like anything anyone ever does, is going to be ruined by their vile attitude.
