I agree with OP, but as a single player. I usually want to RP as my main character, not as the additional origin characters. Sometimes dialogues will just initiate out of nowhere on a different party member that I don't want to be doing the talking and it doesn't make sense that my main MC (or person I want to talk) is standing right next to them but is locked out of the conversation. Also, it's been buggy sometimes (like with the trolls at the goblin encampment) that I will purposefully walk my MC in first to initiate dialogue but somehow someone else gets teleported to them and is talking to them instead.
