Thanks for the support and understanding guys.
CasAngel, at least let us choose at the beggining is what it should be done I think.
Defaulting to the MC would be terrible in some cases. I have a Bard and a Monk currently. Guess which one I usually wouldn't want to default to.
And yes not all skill checks in dialogue are charisma based, but the majority of them are.
It's not even about succeeding. There is a mod that lets you use highest party member modifier but I don't want this. ( and not a huge fan of mods either ) I want each member to have their own unique options when using them.
ie: I don't want to succeed on a diplomacy check for nonviolence with the evil trigger-happy Sorcerer (if there was hypothetically such a companion) just because they have high persuasion modifier.
I want to have his options if I am using his modifiers which only include an intimidation attempt, as it would make sense in character (at least as long as the enemies were no serious threat, otherwise persuasion would make sense too maybe? Anyway you get the gist of what I am saying.)
Has Larian said anything about fixing this issue? To me it's a huge drawback, and it really hinders my enjoyment of the game, which is a shame because it really shines in some other areas
