Title. Let's say one character initiates a conversation with the intention to use persuasion, but finds that for one reason or another that another character should have started the conversation instead. It'd be a bit more realistic AND convenient if multiple characters could be part of a social interaction.
Are you talking about switching PC in multiplayer or being able to switch to one of your companions mid stream in a conversation?
I ask this because (while I have never played multiplayer mode) I saw a video by Larian showing that when it comes to PC dialog that there is some sort of voting system/ ability to communicate with the other people in your party to decide who speaks/ makes the check or has that not been implemented thus far?
As far as being able to just switch between who's speaking in a single player game I am going to have to disagree. The character who carries on any conversation/ makes checks in that conversation should be the character you chose at character creation OR the character you have selected atm dialog begins, but switching between your PC and the companions mid dialog would cause a lot of meta gaming. Ex. I start a conversation with some one as my PC and I am trying to talk my way out of getting in to fight and one of the selections is persuasion, but my character isn't proficient, but I know one of my companions is so I switch to them to make that check, but the conversation progresses and now I need to make an intimidation check, well the companion I just switched to isn't proficient in that my PC who is a Barbarian is so I will switch back to them. So, no... if anything they should allow you to switch who is doing the conversation once per conversation and I say that in part because of the amount of times I have been annoyed that the conversation is initiated by one of my companions due simply to them being closer in proximity to the NPC.
