It would be nice to be able to create "custom" units, for example, ranged units that can also be equipped with melee weapons as well and defend themselves better when attacked in melee through intelligent switching of weapons back and forth. It would also be great to allow better unit upgrading by allowing ANY unit of the same basic type to upgrade to an upgraded unit via a template of sorts. For example if you create a new Dekaren Ranger unit with, say, Titanium weapons, you should be able to upgrade a current unit with iron weapons to THAT unit type without altering the base iron equipped "type" unit in the unit creation list. As it stands now, any time you get new equipment types from an ore source, you have to create and build entirely new unit types if you don't want to alter your base Iron based unit type. Rather awkward and clunky, frankly.
