I'm conflicted about this, I really liked MoP but playing a "classic" MMORPG in my opinion. The entire point for me is the unseen future, the game evolving, having a character I progress and see all this with.
I already played MoP, I already know EXACTLY what updates we will get, I already know exactly what's in the world, the story and everything about it.

I won't have the feeling of playing it for the first time again, nor will I have any kind of hope/dreams of future updates as I know all about it.
