It is easily the grossest and most sweaty frat bro WoW has ever been, and it's 100% because they had a literal attempted rapist frat bro (Afrasiabi) in charge of the expansion.
It was incredibly obvious at the time, too. People are sometimes surprised by it, but entire zones are just coke-addled frat bro fever dreams (Uldum and Hyjal particularly), and I complained about this a lot back then (as my guildmates would attest). I will say literally the very first people I ever saw buying WoW, when I went to pick it up at midnight launch at a Walmart in Indiana, absolutely were Notre Dame frat bros - indeed they brought the Walmart out of copies, I had to buy it from a Target the next day, so they've always been part of the audience, but Cataclysm was when it was obvious they were running the show (WotLK has some greasy frat bro fingerprints, but only on a few bits). It's sad because some of the Old World is still fucked up by Cata trash.
MoP has little bit of the frat bro thing in places but it's very obvious it was a counter-reaction to Cataclysm, it's much more genuine and heartfelt and has less ironic distance, and the humour tends to be more "in-setting" and less "LOL ISNT THIS DUMB AND META" (and even where it is meta it tends to be witticisms rather than entire quests) or, god help us "LOL LETS RE-ENACT THE ENTIRE PLOT OF AN INDIANA JONES MOVIE". MoP actually feels closest to DF in terms of how much is heartfelt/honest-seeming, in terms of the writing.

Nah you're completely wrong. I called it out for this at the time, and I was right to. It's nothing to do with "looking too deep into it", it's to do with entire zones full of cretinous trash quests and absolute idiocy - Hyjal and Uldum particularly. It's blindingly obviously unless you're completely 100% incapable of thinking about the media you're consuming critically. This was long before "social media influence" was a thing, so you're just flatly wrong.
As I said earlier in this post, when you put a literal frat boy in charge of WoW, a man who never grew up, and who Blizzard was literally covering up the sex crimes of, what do you think will happen?
