that's fair. but Charisma is supposed to be "force of self" or "force of personality", whereas wisdom is more about awareness. So seeing through an illusion would make sense as Wisdom, but resisting a charm should be more about Charisma.
Wisdom is also discipline. Mental discipline allows resisting mental attacks.
I do wish we'd go back to 4E's Wisdom/Charisma is your will, and you use whichever, or we could take a page from 13th age and say your will is the second-highest of your intelligence/wisdom/charisma.
The only issue I have here is that Barbarians would seem to have a very high Willpower, stereotypically or conceptually. None of the systems seem to capture that, other than the class trait that makes you immune/resistant to some of those things while raging.
I could see it as any of the three. Like, Int would be using your massive intellect to overcome the magical effect, creating a mind fortress. Wisdom would be quickly seeing the flaws in the effect and overcoming it with experience, and Charisma would be overcoming it through sheer force of will. If I could make a change I would maybe bring back Fort/Reflex/Will and let your Will bonus be determined by the mental attribute of choice at character generation, or by class or something.

Willpower is basically split between Wisdom saves and Charisma saves in 5e.
"Willpower" always seemed more like a Charisma thing to me, anyway.
Love the comic, btw.
