I think one thing that would of helped me was makeing 3 layers of specificity.
Layer 1: simple understanding, this gun is effective against these units and such.
Layer 2: interchangeable weapons and guns. Rpg troops mixed with snipers, like that.
Layer 3: Insanely spesific on weapons and units, Giving some units more health than others, and such.
This would be cool if you would make it so you could go to options and click the "Make my game a little more micro-managing like." Just a suggestion. I wouldn't have the patience to do it really.
