Well, you see, it's basically what they're doing to SC2 as well. I mean, ok fine, I can agree Lich King was a loose end but okay, did they really need to dig up deathwing? Or take a huge dump on all the novels and games like RoC? I mean, the cinematic with Grom dying was one of the most emotional plot parts and they retconned it :/. Also, where the F did Garrosh come from? I doubt that Grom's last words wouldn't have been "take care of my son" when dying if he knew about him. It just makes less and less sense after BC and mid WotLK.
