I figured I'd create this thread as a counterpoint to the existing one, So what didn't work this expansion?
So .. no negative comments! If you want to post something negative, use the thread link above. This is for discussing things that Bliizard ADDED or CHANGED for Mists of Pandaria, that you think worked well.
Monks
Oh wow, I love this class! My main had been a druid right from Vanilla; that changed as soon as I saw the monk. I love the Brewmaster and Mistweaver specs, and Windwalker's a fun DPS spec. I frequently change my chosen specs around and play all 3 a lot.
Dailies
In my opinion, the dailies they added in MoP were some of the best they've done. I've never liked dailies in the previous expansions; this time round I didn't mind doing them. I think if Blizzard hadn't used them for gating Rep grinds, thereby making them feel mandatory, they'd have been some of the most popular so far.
Raids
I've really enjoyed all of them so far, with the exception of Heart of Fear - not as fond of that one. While I can't say I like every fight in the others, overall I've enjoyed all of them.
Rare Spawns
There must be a dozen BoA weapons that spawn at random places in Pandaria. I really liked stumbling across them, and then hunting for the rest when I found out there were more. Then there's the rare mobs scattered all over the place, with challenging mechanics and some interesting drops. There was even a hunter pet, Savage - definitely the most interesting pet hunt I've had so far!
Music
I've really liked the music in every expansion, but I think Blizzard surpassed themselves. Specially the music around the Farm or Shado-Pan Monastery .. I'll quite happily sit and listen in those areas for ages.
What about you guys? What do you really like about this expansion?
