There is also the fact that this is a roleplaying game, and that character with 18 str, con, dext and 3 int wis cha are not realistic at all.

The game was also not balance for "Super fighter" sure, lowering your charisma to 5-6 might be ok for a barbarian. Maybe he never cleaned himself. But how do you explain a character with 3 int, wis, ans cha?

That would be a character that can't speak, can't tell when people is lying to him, and he is so offending you would want to kill him 5 seconds after seeing his face.
