The Classic WF race lasted 41 minutes. Imagine if the real WF lasted 41 minutes. It would be a disaster.
Just because you like something doesn't mean it wasn't a disaster. People liked BfA but it was a disaster. Blizzard thinks it's a disaster. You can tell because if the 50% discount aimed at Classic players . People need to stop hurrying their head in the sand.
I don't know what is needed to fix TBClassic but they cannot use the Classic model.
