It is bad enough that optimizers can't role play a funny character without something mechanical like a 30 in charisma, as a character with a charisma of like 11 simply can't be funny...or anything.
It is just beyond worse when the optimizers go off the deep end and say they must have high, or ''good'' everything to role play. Even when somethings like hit points don't have any effect on role playing.
This is yet another problem. A player will pick something like ''tough'' and then just randomly pick something mechanical, like ''hit points'' and then say ''my character must have a lot of hit points to be tough''. But something like ''tough'' can mean a lot of things, not just ''a got hit points''. And this is where the big disconnect is: the player could just be honest and say ''I'm roll playing and only care about the number of hit points my character has''....but they don't: they whip up the whole optimizing toughness cover and then hide behind it.
And this is the problem of ''master swrodsman'' vs ''demigod of swords''
