You dont get it. The problem with Shadowlands and Draenor plot was that it was bland, boring and "not Warcraft feel". More so in Shadowlands then with Draenor. People get angry MUCH more not when plot is just "boring" but when they feel personally fucked by it. Aka dumbass Grommash "Draenor is free", death of Garrosh (all those "garrosh did nothing wrong" posts spanning miles) and especially Burning of Teldrassil. People can put on with boring plot because its just that - bland and boring. Shadowlands only starts getting MORE flack when it reminds us of BfA and all its screwed up moments.
You should have noticed that trend long ago.
Because of WoWs trademark tribalism BfA was such a disaster, both from writers and fans. Draenor looks like a calm and collected discussion in comparison to absolute flame wars of BfA and Shadowlands related to BfA.
Also i am still not fucken sure how they can reaffirm that YES Sylvanas DID wiped out most of night elves ("race nearly wiped out") and yet also insist on her getting redemption now. Like WHAT WOULD IT COST THEM to say instead "while her plans to wipe out the night elves failed and far more survived then Jailer hoped" or something like that? I mean, they making it harder to "let go" in the same post that implies us to let go!
