You think the 5e designers wanted Strixhaven to come out the way it did? Disturbing thought.I would suggest the tone of D&D 5e books are more than likely mostly established by the 5e team and what they want, rather than marketing; that would explain the difference in MTG and D&D's tone re: Strixhaven.
It would also explain why the film and BG3 have a very different tone; not the same writers or team.
Outside looking in, I don't think D&D has an identity crisis as a game or system. But the differences in tone, themes, and seriousness is going to result when 5e products are not tied to a particular setting or style. Though, I am saying this being unfamiliar with past editions.
Did previous editions have a similiar 'identity crisis'?
