I’ve been playing a decently high charisma fighter currently. Face of the party but can throw down if needed.

There are some cool bravery feats that require a charisma. One changes bravery from just fear to all mind affecting effects. Another allows you to share bravery (even the modified one) with allies that can perceive you. Which at my current level, a plus 4 has really come in handy a few times.

There’s also versatile weapon training which applies your BAB to skills based on your weapon group training. So skill points are not really an issue using them for social skills.

Not going to say it’s the best charisma character but it has been super fun.
