Same here. I have a Fighter main character that goes in the front (because also you can' really make a party formation and I don't want my Cleric or my Wizard to go the first in case I encounter a conversation because if I enter a combat they will die fast) and when i'm faced with conversations I am in real trouble unless there's something involved that I am actually good at (Mostly Intimidation or Animal).

There should be an way to make it work that the character in the party which works best for that situation can be chosen or the option appears. For example if you have the option to be persuasive, the character with most persuasion should be the one to roll the dice and so on.
