Interesting points. Because in many cases I don't feel I see the same.
I'm amazed at how well the story adapts to what I do, and exactly how many possible solutions you have to the Goblin problem. The times it feels "off" is when there's some clear miss-matching in dialogue, but I tend to excuse that as this being EA. (Astarion talking about being a vampire, before you have the scene where you find out)
I agree there's things you could improve, but as consequences of actions go, I feel BG3 is one of the best RPGs to actually do this.
Personally I haven't seen mechanics come before the story telling, but I do feel the story telling is incomplete (and bugged at times). I would love to see MORE interaction BETWEEN the party. I got one scene after a dream sequence where at least two characters interact, which is amazing.
To compare to BG1, the first time I played I got so surprised when the evil party members and the good party members began fighting.
But all in all I feel there's a good balance between story and mechanics.
Especially when you lean into the tadpole power and start getting the dreams I feel an urge to see what happens next, there's a bigger mystery here, that I'm looking forward to seeing.
