In my opiniion, BG3 right now lacks immersion. Let's add up a little. Imagine if you have critically missed, and Astarion shouts something like "i thought you fight better, shit...". Or when you score a nat 20, everyone will react to it, Shadowheart will be glad that the combat will be over soon, Lae'zel will be surprised of our capabilities, etc. etc.
My suggestion is to bring reactivity from companions to combat encounters as Larian did for point and click system. For now, combats are rather silent, that's a bit strange
What's your thoughts
