There could be traits for each troop. Like a trait to increase Hit Points, or a trait to increase Movement Speed. I don't know if it would be a building or not. That is what you can figure out. A Traits System would make each persons troop better in its own way. Like there could be 3 main groups, then each group will have traits in them. Like one of the main groups for a barbarian could be Damage Dealer, and a trait in that group there would be a trait that increases DPS.
If you have an idea that i can add to this, then please tell me!
