Then here did I notice that my units (visually speaking) not to change not on the level of appearance with the improvements on the other hand when I pass at age 4 the helmet changes skin to him but as regards moreover that does not move you know or can one modify that? a track on the file which is necessary to modify?
It depends on what upgrades your talking about. AFAIK (I may be wrong), the champion upgrades via their respective training buildings do have an influence on how units look, but blacksmith and other upgrades don't. I think what you're referring to may be the visual changes caused by gears, and these are not implemented yet.
