Well, I'm going to present a dissenting view.
I hold the uncommon opinion that the Presece attribute vs the cost of Deception, Intimidation, and Persuasion is actually a good thing.
First of all, no Persuasion isn't 90% of Presence. It is very easy to fall into the trap of using just a Deception roll when really a Deception roll AND a Persuasion roll are needed. Deception is the ability to convince someone of a falsehood. Convincing someone to act on that falsehood is still Persuasion.
And Intimidation isn't just about abusing people. Cast your minds back to 1978...
Luthor: Come in, it's open. My lawyer will be in touch with you about the door. Otis, take the gentleman's cape.
Otis: Right away Mr. Luthor.
(Superman just looks at Otis harshly)
Otis: I don't think he wants me to Mr. Luthor.
That scene, in a roll playing game, would have Superman's player saying something like "I look at Otis as if to say, no you're not taking my cape." And the GM should have Superman's player roll Intimidation. No abuse. No violence. But Otis was clearly intimidated.
Now here's the thing, if the cost of Presence was more equitable to its associated skills, 90% of player characters would be walking around with a Presence score of 5 or higher. The player will say "I want my character to be impressive", jack up the Presence attribute, and call it a day.
Because of the inequity, though, it makes people stop to think about it, maybe. At least if they're math savvy. (If they aren't math savvy they just jack up the Presence attribute and call it a day.) But because of the inequity, it makes the players who are concerned about points actually stop and think about their character's interaction skill.
Say, one is building the cinematic Captain America. If one pays attention, one realises that Steve Rogers doesn't have a high Presence. He has a phenomenal Persuasion score (see the Intercom scene in Captain America: Winter Soldier
), and a good Intimidation score ("Before we start, does anyone want to get out"), but Steve is, as Nat puts it, "a terrible liar." Steve's Deception score is low. If he successfully lies, it's because "his player rolled well", or narrative necessity.
If someone is intimidating, and persuasive, and a good liar, then yes, they should have a high Presence. The cinematic James Bond, maybe. Or some versions of Batman.
The other thing that Intimidation in the game does is the "Demoralize" action. Cast your minds back to 1966...
Riddler: The Bomb! It'll go off any second!
Batman: Don't worry. I deactivated it.
Robin: And now we're going to deactivate you! (slams fist into open palm of other hand)
Riddler: There may be only four of us against the two of you. But we're not afraid! (As Riddler slides to a position behind his henchmen).
And for the rest of that round, and into the next round, the Riddler and his goons were clearly operating with a -2 to all their checks. Because the player of kid in the yellow cape rolled well on his Intimidation roll.
I think people forget about these kinds of applications to their skills.
On curves ahead...
That's rabbit's foot...
