Curious what people think of this idea.
What if proficiency gave a bonus to checks against people of a lower proficiency on opposed checks?
So an expert rogue trying to athletics to jump is the same along with trying to grapple someone who's an expert at fort, but an athletics to grapple someone that is only trained at fortitude gets like a bonus +2 or +3 to show that they know how to outperform due to their higher specialty.
That sounds like it might force GMs to give away information they shouldn't have to.
"That's a 16. But is the Duke expert in Acrobatics?"
"You don't know if he is or not."
"Yeah, but it makes a difference to my roll. C'mon dude, just tell me."
"Fine. Yeah, he's expert."
Now, obviously the GM can and should refuse, but having to do so is an extra point of pressure. GMs sometimes fail their Will save.
