If gameplay is compelling people will play it. If gameplay is not compelling people will not play it. MOP was not my cup of tea because it put such huge rewards on aspects of gameplay I dislike that I felt it was necessary. Point and case was the original dailies in mop.
Now blizzard is forcing us more so into open world end game content instead do instanced end game content with their overall design of WoD. People do not skip over content they find fun. Forcing players to participate in unfun content because it is cheaper to develop than say 10 more dungeons is bad policy. Removing flying so people do not skip content they find unenjoyable is dumb.
I have like every expansion up to mop which I hated. That makes sense because the second I dinged end level for each expansion I stopped playing open world and switched to instances. I can only hope Blizzard goes back to putting in 20 or so dungeons in WoD like they have in every other expansion. My gut however tells me we are going to get forced into open world bland content that will only be played because blizz forces it's community to play it
Blizz had such a winning recipe vanilla - cata. Let's face it cata was fine it just contained half as much content as other expansions. I can only hope blizz looks at MoP as a guideline of what not to do.
