In battles you can see what the future waves health is and how many strengths they have. Often the most important strength to know is how resistant they are to physical or magic damage. That is not showed in the future wave thing. If an enemy happens to be 70% resistant to physical damage your plans can be rather messed up if you have lots of physical units. Of course, after a while you learn what their resistances are and learn to check their resistances early but it’s rather annoying initially.
Could you modify the wave things to show how resistant they are to physical damage and how good their evasion is?
