I'm curious as to why the game doesn't have any sort of experience system (or at least I can't seem to find it), where troops that have participated and won battles obtain some experience per kill. (To my awareness none exists, even though there is a kill count for units).
This would serve to offset the cost of defense, because if you are invaded, and successfully fend off an invasion, all you have are a bunch of injured soldiers and casualties. You are essentially set-back from a military perspective, and successful defense of invasion yields practically no rewards. Troop experience would be one such way to remedy the defender's curse.
This also makes gameplay more dynamic, you are encouraged to spend time healing your valuable experienced troops rather than focusing on pumping out more.
Finally, it adds a dimension of realism to the game. Battle hardened troops perform better than their freshmen counterparts.
