Hospital for troops

I have an idea on creating a HOPITAL for the troops that have been injured in Battle it will not give the troops just like that it will depend on the health of the troop..let's say a giant was taken half its life the hospital will regenerate it for half the time and half the cost or something like that tbh I don't have that much info on how it will work but it's just a suggestion if anyone wants to add something you are welcome to do so it seems like a fair deal for the troops we spend on battle and don't die plus the economy is not the best atm...

Keep clashing :-P
