It's funny that I come to this same conclusion by just reading about WoD content, and didn't get into bet. Couldn't agree more.
There's not much to look forward to WoD. They've done a few things right, but others... tend to grinding or progression.
Garrisons, lack of flying, all this "go out in the world" content thing which is just "pointless stuff to kill for the sake of loot, just like Timeless Isle", etc. It all kinda shows as if they were trying to increase the expansion 'life spawn'.
Usually, I would have to fight not to play WoW, but after WoD and a bunch of other crap coming from Blizzard, I'm fighting to find a reason to come back. It just doesn't feel like they're trying anymore, but simply spending the minimum amount of effort possible to release an expansion in order to profit.
