You are right, some free military units are required to protect the first settlements. However, I'm not sure that Conquistadors are the good variant for all civilations. Conquistadors are OK for Spain and Portugal, but how about other ones, e.g. Dutch, England, Sweden, Russia, etc.? I don't comment the cannons because up to now they are working by the wrong way. Cannons can capture the enemy cities (How it's possible? ), instead of bombardment of the enemy army located near my city, cannons can only attack my enemies as "a renaissance mobile artillery" (Why? ), etc. Fortunately some improvements of the Cannons work are planned by Raystuttgart in the future. Next remark. You are fully right, the healing must cost someting. However why do you use "food" for a healing instead of "medicaments"? I remember this yield in one of mods published earlier. To my opinion "medicaments" are much more effective remedy for healing than "food". "The food is taken from the city with the highest food storage at that point". It's OK if your wounded unit is located near or in this city, and as minimum inside your border. However how your unit will heal if the city with the highest food storage is located too far from your wonded unit, e.g. on other continent? Here probably a new emergency food (or better medicamets) supply unit would help? Thus, your invasion army (on other continet or outside your border) will have: - some army units (veterans, etc) - some cannons - emergency food (medicamets) supply unit In this case your wounded veterans will heal by using food (or medicamets) from your supply unit.
