So I was watching a video from Blizzcon 2010 Q&A and I've noticed that devs doesn't know anything about their game. They doesn't give a sh*t about lore or anything else. Just take a look at this video. Play it from 4:10 to 4:50 and from 4:51 to 6:58:
Now I know why Cataclysm was so terrible and why MoP continues it. WoW is losing subs because of devs that doesn't care about anything.
