Yeah, the proximity dialogue is pretty terrible in BG3. Often ignoring the main character and pulling in someone else randomly into a conversation. My breaking point was when Mayrina pulled Lae'zel to talk with her, who couldn't care less about her situation, thus utterly shattering my immersion which started my very first thread on the forum because of how bad it is.

Hopefully they rework it or improve it because I cannot imagine playing the full game with the proximity dialogue like this.
