> The other issue is whether a unit ought to be priced in comparison with units of its own nation at all.
Yes, you must. Otherwise units of your nation will be obsolete (not that there are not obsolete units in dom3
, but it is good to keep the numbers down). Nations are not balanced vs other nations based on the cost of the most popular recruit, they are balanced as a whole.
So try to keep units relatively balanced within the nation and if they are too expensive compared to other nations, lower the cost of all units of the nation. This way you get the nation internally balanced, which is preferable.
