We could improve the Han Ministers with new props (specifically head gear) and textures. There were 9 of them, so it would be nice to have perhaps 9 variations.   (Two in the back^)

UPDATE 0.3.0:     Added new tactics, 5 in total (Attack, Building, Defense, Economy, Research).     Added the ability to switch to any tactic with a single click     Icons have been added for each tactic     Switching does not require resources, but as the Hero's rank increases, the switching time increases (rank 1 - 5 seconds, rank 2 - 10 seconds, rank 3 - 15 seconds).     Attack - bonuses to the attack parameters of units and buildings.     Building - Reduction in the time and cost of building structures.     Defense - bonuses to the defensive parameters of units and buildings.     Economy - bonuses to resource gathering, but the attack and defense of units are reduced.     Research - reduction in the time and cost of researching technologies.

The Romans would have everything and that would be unfair to the others civs. There should be different versions of Rome.
