Does this approach work for you with the 'party face' system of BG3? It often sucks your MC into the cutscene and there is currently no way of taking over the convo with the other character or even delegating skill checks to companions.
It's a principle I apply in general regardless of the direct benefits, because I simply enjoy experiencing as much variety as possible across a single playthrough (and while I MAY gladly choose to do multiple ones on my own and experience different things, I don't like to feel like I'm pressured into it out of strict necessity).
About that specific topic, I had a laser-targeted thread I made specifically to discuss it in the past:
https://forums.larian.com/ubbthreads.php?ubb=showflat&Main=101623&Number=826412#Post826412And a key passage that to some extent answers directly your question may be this one:
Maybe I'm weird but it doesn't really matter to me. I don't want to pick the Face as matter of min-maxing. I just want my character to be the "protagonist" even when there are better diplomats in my party.
Last thing I want is having to handle every dialogue with a bard, paladin or warlock companion only because I'm playing a Barbarian, for instance.
I'll deal with the consequences and occasional shortcomings of being a barbarian if I have to.
Admittedly the entire thread is a bit redundant at this point. We'll see what Larian is setting for, but I kinda gave up on the idea of having "your party participate to the conversation".
I doubt it's going to happen even if Swen Vincke at some point promised it would.
