As far as the leveling grind goes MoP is by far the most enjoyable WoW expansion to date. The zones, and quest lines are generally pretty cool. It doesn't feel tedious questing like it did in Wrath and Cataclysm.
The dungeon difficulty between 85-90 seem well balanced as well. They're just the right level of difficulty so that you actually feel like you accomplished something when you finish one, but they also don't slow down your leveling progress by being far too difficult.
They've also completely re-done the talent trees/specializations. Everything is a lot more stream-lined now.
