I disagree ... with the title. Because it's incorrect.
PC stands for Player Character. That's the one character you create at the start of the game (or several, if/when it becomes possible to create a full party of PCs, but I currently treat this as an edge case).
The other characters in your party are your Companions. And they are also NPC (Non-Player Characters), like all the NPCs in the world that are not Companions.
What I wholeheartedly agree with however is the request that :
We should be able to change the Party Member who does the talking, and rolls on an Ability Check.
(Regardless of whether the current speaker is your PC, one of your PCs if you created more than one, an NPC Companion, or the PC Companion of a friend you're playing with.)
There are so many good reasons why this would be much better than the current system, but I won't go into them. This request has already be made dozens of times, the explanations have been given, and my purpose in this post was mostly just to add my +1 to the idea of the request (by the way, it's still possible to change the title).
I'm not holding my breath until I hear Larian's response to this, but I'd be quite interested to know, at the very least, if they have any plans to rework the conversation system. Or, on the contrary, if they're happy with how it is and plan to leave it as it is. Swen announced in the last PFH that Larian is starting to see the end of the project, so maybe they are starting to stop brainstorming new ideas (like new ways to make Throw the main action in the game), and have an approximately finished list of features to work on.
