It's doubtful that this is even 100% the case. Afrasiabi, senior creative director for World of Warcraft, was fired was fired in June of 2020. Production on SL was well underway in 2019. Among the very first things established in the infrastructure of an expansion is character arcs and story beats which would be earlier than general production. This is so that the cinematic and cut scene teams can get on with their work as well as the quest writing team. The timeline does not support that SL was Danuser's baby in any way. I'm not trying to whitewash Danuser here; just pointing out that Blizzard's leadtimes lead to a lot of stuff being settled very early on, usually before serious production starts. The writing team is indeed a team and their output will be the output of a committee and watered down due to that. Even the writing teaw is following an outline created by someone. That someone would seem to be the Creative Director for World of Warcraft (Afrasiabi). It's silly to imagine that given the history there that Afrasiabi wasn't the major drive behind the story of SL.
