What really amazes me is the notion that WotC would agree to a change so likely to result in first time D&D players having a bad experience.
Oh yeah, lol. Players will start with the freedom of BG3, making all types of wacky-but-still-powerful multiclassed characters. This might encourage them to try PnP D&D 5.5e, expecting to basically understand the rules and create similar characters, and WHAM they'll be hit with tons of restrictions that severely limit their characters' strength, available actions, and flexibility.
