Experience

Ranking up would be cool. This is a thing in command and conquer and other RTS games. Healing is always a heated topic here. Im curious how much gold is used to heal units. I cant imagine very much. Veteran units could be a thing. Perhaps add a healing effect to then over time as a reward. Or make them more efficient.

Don’t you hate it when a unit kills 500000 other units but is on low health and useless since apparently they learned nothing from all that experience killing shit?

Exactly!
