I think there should be a formula format so that a specific equation isn't tied to the engine. This will be useful to damage calculations, gained experience, cost at shops, etc, It will maybe be expressed in JSON, or a python function. What do people think?
I'll just comment the same as I did on the github issue. I don't think JSON is the right format since the calculations already take more than a single line, and the supporting code to parse the text and pull values from the game could get complicated.
I do support organizing them better and making them interchangeable though.
