[Warhammer]

After reading the entire thread, I think this is best/most easily solved by increasing the upkeep or the initial cost of the sacreds. Once you get in the realm of changing unit stats such as strength, armor, etc., you change the balance between nations too much. Tweaking the cost of the units preserves the uniqueness of the units, and allows for a more moderate tweak. It might take a couple of tries to settle on the exact costs, but it is the easiest way to handle it.
