As I'm asking a lot currently: yes, that's idea - does it work?Maybe a minority here, but I like it. As I recall from reading dev diaries, the idea behind monarch points was in part to help good rulers and bad rulers feel different.
Mana, in my opinion, isn't bad because it's sloppy design, because it's abstract, or something. It's a system that doesn't work, and that's why it's bad.
