This is a specific issue, but asks a larger question which is: in a narrative "yes and" system, when is it ok to say that something doesn't work?
My example. A character with Charm is attempting to get past Stormtroopers. Charm is opposed by Cool, based on Presence. Stormtroopers have Presence 1 and no Cool skill. This means anyone with a decent Charm skill is going to be able to charm Stormtroopers most of the time, as the difficulty is 1P. Not very tough.
Stormtroopers are described as "implacable foes" with Sergeants being "calculating fearless individuals with a reputation for efficiency and an absolute lack of mercy or any emotion in the execution of their duties".
I can imagine charm working in certain specific circumstances, but most of the time it should not even be possible against these guys. I don't think even upgrades or setbacks cover it.
What do you think? Is it ok in some situations to say thematically "That won't work" even though, mechanically, there are rules to do it?
