So I created the Follow role because in recent playtests I found that designating a specific person to really focus up and play off of the Lead sort of gave them "permission" to make bigger, more interesting choices. I don't think tables where everyone already knows one another have a problem with that, but when you have strangers playing together, you get some awkward silences because no one wants to step on any toes. Or you get the opposite, where one person sort of dominates the whole session.
*That being said*, I really like your idea of combining the Follow and Backing Band for tables that want it to be a little more freeform, so I added it in as an alternate option!
As for where to put the note about rolling, I went back and forth on it :/ I even tried making it an inset, but it just interrupted the flow in a weird way, and in the end I put it at the end because it really is less of a rule than a soft guidance. Of course, I'll probably change my mind again. Such is life.
