My favorite is everything from going up to level 90, working on professions, the new dungeons and raids, pet battes is really fun it reminds me of playing Pokemon when I was a kid. There is more to talk about with the new gear and changes to customization with the points instead buying new gear. The challenging mode is also interest with that I like to how fast my guild can go through.
AoE looting, and the ability for multiple players to 'tag' mobs of importance, like quest mobs. Now, we don't have to snipe each other to do these millions of dailies!
Honestly, I really like how the world feels so much more alive. There is always something to do for whatever mood you're in and you see other players out in the world (of warcraft).
I like the new areas and questline so far!
Account wide mounts and achievements are quite convenient but the new raids are fun.
mine is Valley of the Four Winds and The Tillers
My favorite part of MoP is having your own Farm. Love coming in the next day and harvesting my crops.

The way the dailies actually tell the story of the area, rather than the previous "go there and kill this or do that because I said so" feel of the WoTLK dailies.
AoE looting for sure!
The Raids, The bosses are great fun, and the loots, omg the loots.
My favorite part is the pet battles!
So far my favorites are the AoE looting and my monk, it's nice to get to learn a new class all over again!
My favorite thing with the new expansion is all the new pets, and with them, the pet battles, so we finaly have something to use our collections on :)
AoE looting is the best!
