As an ant-RDFer…
So yes, I would use RDF but I wouldn’t be happy with the decision to add it back into the game. It would also be a signal that Blizzard would cave under the pressure to provide the same QoL tools that retail originally introduced… and to eventually make Classic players quit the Classic experience like they did with retail.
I would stay for WotLK but I would be less interested in future Classic expansions.
