I wonder how big a percentage of people who didn't like MoP don't like it only because of the whole pandaren/Asian theme.
Also see a lot of posts saying it was so bad that they quit after a few weeks or months. I don't think you can say it sucked when you only played a small percentage of it.
I agree that the story sucked, but the gameplay (at least on the PvE end) was very good.
-3 decent sized, solid raid tiers
-More non raiding/non pvp content than ever (Brawler's guild, pet battles, proving grounds)
-Introduction of Flex
-Mediocre story (not a huge deal to me)
-Lack of 5 mans
-Making LFR into a staple
Not quite as good as Wrath, but miles ahead of Cata for me.
