@HelloRaptor, I disagree. That's still about trust.
But then again, I also never run scenes with my character in them and then pretend my character can't do something that would be applicable to the scene. Instead, I build the scene in a way that my character is only helpful in things that move the plot along for the other characters where it comes to things that only my character can do.
So it's about trust, and it's also about storytellers not being lazy and actually putting some thought into what they're running. When I ran combat stuff with my combat-capable Sin-Eater, he was in the thick of it, usually off to the side. Maybe he was handling mooks, and so something he could do easily had to be done by someone else, or whatever.
A few times he just stood there and let other people handle it because he was mentoring them and being a jerk about it.
It is about trust. It's also about storytellers not writing themselves into a corner. I mean, shit, I thought that was a given.
