Hussar
Legend
Since when has WotC moved into original material? When was the last time created a new campaign setting (created themselves, rather than publish someone else's setting under their brand)? Of course, maybe the writers do want to do that and the corp-types are stopping them. In that case, WotC is in fact curtailing their creative expression.
Wild Beyond The Witchlight - original setting and adventures.
Journeys through the Radiant Citadel- ten or so original settings.
Strixhaven - original setting.
Just because you don’t like them doesn’t make them not original.
