I see it as the Reactive category is the more dramatic scene based portion of an RPG and the Responsive suite of behaviours is more the ‘downtime between adventures’.

I’m sure there is an algorithm somewhere that determines the perfect blend of drama and repose for any rise and fall narrative. But the thing I found so enlightening about ttrpgs was when I discovered that you could still consciously foster immersion and be separate from your character. (Burning wheel was to blame I think).

There is some innate human curiosity to experience all the reactive stuff, even if so damn unproductive, and its sure as hell exciting to watch as audience. But as players, the responsive suite is vital to maintaining good table relationships with your crew.
