Talking doesn't rely on Charisma, unless you're trying to manipulate someone. If you just want to talk, then that's one of those things where you don't usually need to roll dice.Finally I disagree that everyone can dump charisma. A good portion of our game is interaction based and we roll plenty of cha checks during a game. Unless only one character wants to fully participate in a big section of the game then several characters tend to have some sort of cha focus. Its pretty boring when only one person does all the talking surely.
Maybe you do it differently, though.
