It's actually only a problem if the group isn't into realistic social interactions. Look at the real world. People who don't speak well almost never sit back and let the one charismatic person in the group talk to someone. They like to chime in as well, because people want to be heard and communicate.nah the law of consequences will fix that either with Barbarian learning they suck and keep screwing the party or they piss off some important NPC and die. This is only a problem if the DM refuses to DM properly.
Critical Roll is an excellent example of realistic social interactions. They all talk and interact, from the PC with the high charisma and proficiency, to the PC with no proficiency and a charisma penalty.
My PCs are going to interact socially no matter what my PCs charisma. The rest of the group doesn't get to shut down my enjoyment.
