Yea, I designed units of course. The problem is they still have 5 hp. If i make a fully upgraded peasant army, it will cost like a ridiculous amount of money. And then they will instantly get slaughtered by monsters. 5 hp is 5 hp
I was hoping the upgraded units would have more hp / base stats. I even gave them cool names. I think the problem is the army's are just terrible compared to the champions. I can have an amazing champion at turn 15 whereas it would be like turn 500 before I can pull off a fully upgraded peasant(10) army that would still die to my turn 15 champion!
Their stats go up based on the gear you give them. I don't think we can do magical gear becauase the magic tree isn't implemented.
Their HP goes up with the training option. When you want to train the troops, there's options at the top like normal/veteran/elite. Those increase the build time, and increase the HP of the units.
As to the last point, your standard units aren't supposed to stack up to a champion. One champion probably won't kill 100 archers, even if each archer only has 5 HP. The armies actually work fairly well I found, I had a squad with bows and they dramatically boosted the power of my Sovereign when grouped together.
