Hmm... my favorite new addition would have to be Monks. I've had more fun leveling my Mistweaver with my friends than I did all through the last expansion.
I love the more in depth story lines in MoP. The Lorewaker cut scenes are great!
My favorite part of Mists of Pandaria so far has to be the Pet Battle system. I already loved collecting pets as it was, but now this gives me more ways to collect pets. I also like how you can challenge other people to battles and even share some pets with my friends. More ways to share fun with my guild and friends.
Story lines and pet Battles.

Favourite are storyline, AE looting and pet battles! For me Mist of Pandaria is the best expansion!
Favorite part of pandaria has to be AE looting makes farming so much easier
I love the AoE looting the most!
My favorite part of MoP is the whole theme of the expansion, previously we've had invading forces and dark themes overall in TBC, WotLK and Cata. Finally seeing an expansion with colorful areas and a race that is cute, cuddly and funny together with a class that fits it perfectly is such a relief!
Favourite part is the pet battles and AoE looting
The challenge mode for sure.
Crystal of Insanity : )
My favorite part is the pet system. Not necessarily the battles, but being able to collect the critters crawling around everywhere and being able to flaunt my collection.
I think the overhaul of the talent and glyph system is spectacular. Gives a really fun way of adapting and changing your character fight to fight to ensure you're going to perform to the best of your ability.
The things I most like is the ambientation and the music, those are just awesome and let you stay in a place just to admire them. *-*
I love the PVE content and new mounts
i like the questline where the hozen falls in love with the undead :D
