I have a nice idea, but I highly doubt it will even be considered. After each upgrade of Units and Heroes, their appearance should change slightly, Goblins got a little more beefy, then maybe a little slower. For Mad Bulls maybe their weapon could change slightly, from a wooden hammer to an iron hammer, and so on. Who thinks this would be a nice little addition to this already great game?
