Afrasiabi was fired in June 2020. Well enough into development, but not 7 months after Shadowlands launched, and certainly not enough to have had a direct impact on poor writing choices they themselves made on the fly.
You also can't say someone is a toxic saboteur trying to destroy a character out of spite towards Kosack's Garrosh writing, which is the narrative posed by those same VAs, while also saying they're responsible for writing that consistently rewards and softens that same character. It's incompatible.
Delusions are delusions.
EDIT: I hope Tinkers happen so I never need to see threadshitting about them ever again.
