Larian has proven with DOS2 that they can do really great roleplaying.
But the DOS world is their own creation. Players had no expectations of the game and were unbiased.

I carry 10 years of D&D TableTop experience around with me. I expect a D&D computer game to feel like a TT game.
BG2 has done that. Also there were deviations from the rule system, but these did not undermine the D&D game feeling.
I expect exactly the same from a BG2 successor.

But BG3-EA does not meet this expectation. The DOS2 game elements are much too dominant and do not really fit the D&D rules.
At the same time, many D&D rules are implemented completely unimaginatively. A game master who lets everything be decided by the dice in every conversation would soon be out of a job.

I think Larian has massively underestimated this expectation. The question now is how they deal with the protests.
