Unfortunately Blizzard has had a problem for a long time where they are too stubborn to listen to player feedback about WoW. They will put systems into the game that people hate, and for years they will insist that the system is fine and meets the team's design goals, despite all the people telling them that it sucks and isn't fun. Then, finally, in some future expansion they will go "yeah guys that really did kind of suck" and remove or overhaul the system. They really don't have a culture of listening to player feedback, and it drags their games down.
You'd think they would have learned by now, as they repeat the same exact mistakes over and over again. It's like they hate their playerbase.
