from the rules:
This move action cost is a simplified way of representing any number of different ways you might go about shaking off the wide range of banes you might be afflicted by.
Key word there, is, it is a “cost”, it isn’t really an action roll. It is a cost to wanting to get rid of a bane. This way banes have more of an impact if you do shrug them off. The reason I mentioned Provoked and Demoralized being minor was up above.
Now, the GM is always free to change things up if they feel like it, or to make a game feel gritter/harder.
If a bane has a huge exceptional success (15+ over defense for example) maybe they will auto apply disadvantage to resist it.

off to the dentist now though, so will have to wait to reply to anything else for a bit
