Oh, I just write in another thread here: The longer I play BG3 (over 100h now) the more I feel Larian does use DnD only as a flavour, not an actual mechanic which drives the game. The game is driven by story and visuals. Frankly, it may worked out for them. Even tabletop DnD can be driven solely by story and fantasy with minimal usage of actual rules. It's just not what we nerds are expecting.
