A new trend I'm seeing recently, is people stating that MoP was a fantastic expansion. That it did a lot of good things, but the key problem with it all which was so bad that it ended up bringing the whole thing down with it, is that the fantasy asian theme and Pandaren do not fit, and that a former April fools joke should not have been made a race.
On the other hand, there is never anything ill ever spoken of TBC, despite it having the same issue, arguably much worse at that.
Starting with theme: MoP was a fantasy asian setting, in a setting where other races already had some asian influence (Nelf and Korea and Orc and Mongolia, for example).
On the other hand, TBC was a science fantasy setting, where no other races had really strong science fantasy roots, save for Gnomes, who ended up moving further down that path -because- of TBC, and even then were less scifi and more steam punk.
I am not saying either is wrong, but why is TBC free of criticism, when it has such giant theme shifts. Suddenly we had elves flying space ships and our demons are actually aliens from space. What did MoP do? Suddenly our Orcs with samurai heroes were meeting people who fight with their fists?
Then there is the issue with race.
MoP added Pandaren. A race that was once a april fools joke, but were none the less established in canon from WC3 TFT on due to Chen, and mesh well with the races of the game.
TBC added Draenei: A race that only exists due to a retcon, weren't really hinted at prior to TBC, ended up messing up the light lore pretty hard with their gods (even fucking with night elf religion later on: Elune is likely a naaru), ended up sticking their fingers all into Orc lore, and are a blatantly sci-fi race in a fantasy setting.
Yet Pandaren are the ones who are complained about. In this case I will say its bullshit. Draenei are a giant lore hole that simply do not fit to the point where blizzard has even admitted they dont know what to do with them. But, why are they not criticized for this. Why do Pandaren ruin MoP for being an april fools joke. But Draenei do not ruin TBC for fucking the lore 6 ways to hell for both horde and alliance?
