Well I would like to see a means to change production, but not like HoI4, but more like War in the Pacific. Subtle changes or enhancements would be great, or decisions like NOT to produce the Tiger at all, to free up those resources to build more PzIVs, changes that could have been made. Or as in WitP, the ability to train units longer, or whatever. All of this could be alternate settings.
