In WotR I was overwhelmed by the incomprehensible wall of Feats the game was throwing constantly at the player.
With BG3/DND I was underwhelmed. Didn't like that I have to chose between ASI and Feats, it feels very restrictive. With the the limited amount of available subclasses and the lack of "prestige classes" in the game the builds can become a bit schematic. Many will try to bring "flavor" into their builds with multiclassing, but it's harder for beginners and you may easily lose a Feat on the way.
Bottom line: Gimme more subclasses please (and stop forcing Thief dips onto dual wielders). Variant Human sounds good too. Changes to the DND system? Not unless the DND veterans here signed off on it (not even kidding...)
