I think a much lighter touch on a future attempt at Classic+ would be their best selling product.
But I don’t really see this team as having the finesse necessary for that. They made some really great design choices for the raids in SOD, minus the borrowed power garbage in Naxx and the heat 3 joke in MC, but their class design/rune/power creep situation is just a disaster and has been unmitigated since launch of SOD.
I’d love to see the “lessons they’re taking” from SOD into future Classic Plus-esque products.
