I agree BG3 is an enjoyable video game as it is, and I would say Larian have managed to balance the views of the different player groups ( BG/FR fans, DIVOS/General videogamers, and TT 5e players ) quite well.
BG3 does not NEED to change its game-play to be successful.
BG3 could BENEFIT from offering options, where practical, that would help players tailor the experience if they don't like the balance Larian have chosen.
Obviously much of the game content has not been completed, and obviously there are functional problems with the clipping/animations and conversation/state management, which I'm sure Larian know perfectly well.
Beyond that, Larian are more likely to listen and respond to player feedback where it concerns HOW players interact with and control the game - UI, input methods, camera control - but I do not expect any significant changes to the way the game works.
Nor should there be significant changes really, since Larian were perfectly open with everyone who has bought into EA, showing off multiple gameplay streams. BG3 does not fully meet my preferences either, but I still bought it on the basis of what I had seen, not some fantastic expectation that the game would change markedly.
