In Elemental, you design your own units. Give them whatever name you want to give them, equipment them with weapons, armor, helmets along with deciding how much training they need.
Creating a soldier or a scout or a knight or what have you boils down to how long it takes you to have the equipment on hand and training which is raw time.
There is still "quick build" but that simply, at a cost, gets supplies to that town a lot quicker. It's like having your "stuff" sent to you via Fed Ex Air rather than UPS Ground.
So we're still playing around with this concept so would love to hear thoughts on it.
