I think you are totally right! We should have thought of that when making the book.
Unfortunately we are a very small team and right now we are focused on promoting the game and adding more content like maps rather than making big changes to the book itself.
We will, however, run an UMA RPG campaign over at The Harmacists (https://www.youtube.com/@theharmacists5454) hopefully in a couple of weeks. The campaign will serve as a great example of how the game is meant to be played.
Thank you for your feedback!
