For me the biggest areas would be to have meaningful choices that cover a reasonable range of choices, and then have real consequences following from those choices; meaningful reactivity from the world to my PC; my PC being central to the story; using the DU concept to provide a range of PC choices (while dropping the "origins" concept); a more balanced distribution of alignment personalities for my companion choices; no railroading; meaningful ways to avoid combat where the outcomes are not inferior to the outcomes from combat; the game being playable with a range of party sizes; and, ideally, a move away from DnD mechanics.
I'm gonna be totally honest, I totally don't get the last part. BG3 is probably the first game of this kind where *I'm not* worried that solving things peacefully will result in getting an inferior outcome. In fact, it's the opposite. I try to solve things as peacefully as I can in this run and it always feels rewarding. Have you really checked that part, because it really isn't true. At least it's not my experience and I also don't like to miss stuff.
