People aren't going to be happy with a new expansion's story and setting until it shoots us into the future and everyone forgot about us, so we're just murderhobos again.
Which MIGHT be the 10.0 story (expecting Azeroth again, maybe timeskip due to Infinite shenanigans).
I personally feel that Shadowlands has a touch of Pandaria to it where we're fish out of water, but I know the "Maw Walker" thing will sour people.
