Barbarian King and Archer Queen Upgrades
Ok first of I would like you to know that I am fine with the fact that it takes a builder to upgrade the BK and AQ. I am even ok with the progressively longer build times for these upgrades because it gives you something to keeps striving for. The thing though that I think needs to change though is not being able to use your heroes while they upgrade. I can see not using your barracks while upgrading because the total upgrade time is insignificant in the time it takes to upgrade to max. For each hero it will take 227.5 days to upgrade to max so that is 227.5 days not being able to use your hero. I'm not asking to reduce the days taken but please allow us to use them while they upgrade.
