I have a character with 7 Int and Cha, 11 Wis. He's somewhat aware that he isn't the smartest person in the room and often the opposite, so he tends to let his fellows do the talking and when it comes time for action, he can do that. He is never involved with making the plans, never uses complex tactics, and is perfectly fine with being looked down on because at the end of the day, if he takes the beating, he can get a new scar and make sure his fellows walk away alive.
