shouldn't cha determine will?

[Swordgleam]

D&D tends to say "i'm logical!" then giggle like a schoolgirl at it's joke.

I might have to steal that line.

I really like the way 4e does defenses. It makes sense to me that Charisma is part of Will if you think of Charisma as being not just prettiness, but "force of personality." You can have force of personality, resist mental domination, and still make very poor decisions. (That sounds like most of my friends, now that I think of it.)
