Given the scope of BG3 and the large number of initial sales. I would expect Larian to have received 10's of thousands of bug reports. Its a truly monumental job collating them, weeding out false reports, prioritizing, and then fixing things.
I suspect their main early focus is on game breaking stuff (crashes) and building out cinematics (which take a lot of time . . . and is a whole different team of employees).
Play balance and rule changes will come over time . . . although given everyone has different ideas about how things should be . . . well we aren't all going to get what we want.
So far in just 3 weeks we have had two major updates, both with nice communication pieces. That is more than enough for me.
