Nah, only pretty childish people were. Mostly dudes who want WoW to be HARDCORE!!!1111 with some bloody muscled orcs beating down on bloody muscled humans. Ignoring that ever since the start, WoW had an extremely diverse world with peaceful native american cow people, tiny pink-haired geniuses in cogwheel machines, and so on and so forth. Blue goat russians from space and british werewolves are sensible, but asian panda monks are "taking it too far"? I just don't see it.
I enjoyed MoP thoroughly, the design of the zones was some of the best, I liked all the new stuff that they tried and introduced (scenarios, challenge modes, pet battles, the farm "friendship" thing, the Lorewalkers stuff, treasures around the map). I also like the Monk class, and class design in general was amazing. (I very very much miss MoP-style Elemental Shaman, Disc Priest and Ret ...) Since I also enjoy dailies, I didn't have a problem with them like many other people. All the patches brought pretty cool and new content OTHER than raids: Isle of Thunder, Dino Island, that Horde v Alliance thing, Timeless Isle.
I really don't have much of a bad word to say about MoP, other than that I find it very sad that the Vale was permanently destroyed and hasn't been "healed" yet. Kind of sucks seeing it nowadays. Oh, and the dungeons were too easy and didn't offer much after the start. Also, no new dungeons were introduced over the course of the expansion.
I also mostly liked Cata. It had some flaws, like Dragonsoul being not too great, scrapped content like the Neptulon raid, and the fact that the zones were all spread across the map, not giving that distinct "expansion" feel that comes with a whole new continent. Oh, and healing being a total bitch at the start.
What I really liked about Cata: the dungeons! The starting dungeons, the Troll dungeons and the endtime dungeons. All great. Also transmog and the Firelands daily area.
The only expansion I quite strongly dislike is Warlords. For a player like me (no raiding), it offered me very little. The questing was nice, bonus objectives are a good idea, and SMV is super pretty, but that's about it. The dungeons were alright, but offered nothing as the expansion went on. Apexis was awful. Reputation was AWFUL. So much content with potential was scrapped (Farahlon, Tanaan only in 6.2, Shattrath, Karabor ...). There were only two patches, and one of them was "that" patch with garrison updates and the selfie camera. Which btw I don't hate, but come on, that's not patch material. Compare with MoP's patches! The garrison itself wasn't an awful idea, but the almost non existing customization (all in Human and Orc design, and you can't choose a zone ...) ruined it for me. Plus the fact that there was almost literally nothing else to do, so you logged in to your garrison, did the missions, and logged out. Ughh.
For me personally, I'd rate the expansions I've actively played as follows:
Legion >> Wrath and MoP >> Cata >>>>>>>>>>>>>>> WoD
Wrath is only on par with MoP because of the story, the theme, and nostalgia (since I started back then). In terms of actual content and features, MoP would probably win out.
