Kind of...perhaps."in-game advantages"?
Isn't refusing to be intimidated by somebody who should intimidate you be a huge liability? I could see that character type causing all kinds of problems for the party.
Unless, of course, the NPC isn't actually, really, justifiably intimidating, but just rolled well at their "Intimidate check".
But do you see my point?
And this brings it right back to what I said about 75 pages ago: if PCs can choose to ignore these things there's no justifiable reason why NPCs can't make that same choice, which makes the very existence of those skills pointless. Get rid of them.
