Wow is getting boring. The game suffers from a bigger problem. The underlining mechanics of the game have gotten boring. Wow needs changes in game philosophy and direction. Blizzard needs to shake up the core of wow.
One of the reasons why I think core mechanics have gotten so boring is because we have had the same designers for like 6 years straight? You need new blood and new leadership thrown in from time to time to shake things up and keep them from being stale.
Eventually having the same designers gets to the point were nothing truly new gets introduced just rehashed stuff we have already did a million times over.
This echoes a lot like my signature below which was originally created by none other than Albert Einstein.
