I want more D&D rules because I believe the gameplay - combat, exploration, class balance, immersion - will be improved over Larian homebrew in many of the cases and make BG3 a better game. Furthermore, it will more easily allow for people to play their favorite PnP characters in BG3 & vice versa, as well as enabling custom D&D 5e campaigns to be created using any possible BG3 editor.
The discussion on Larian's (original or more recent) advertising of BG3 is somewhat relevant to the topic of "Is more D&D rules good?", as people could be (and are, as expressed by various posters) disappointed at the lack of 5e rules which might affect enjoyment. But more 5e rules doesn't necessarily make a better game, so it's best to make arguments as to why/how rule X would improve BG3.
