Aqizzar:
I see how this would work. I have some hope that there would be some actions that take higher stats.
For example, a unit with a really high B might be able to charge through enemy lines, provided it has a good F stat, too, possibly wounding a unit or causing a unit to panic. This would only become viable with a B of ~9,10. Of course, this would only tactically work with other units to help clean up the mess, as the unit with high B would now (probably) be surrounded. This would solve the diminishing returns problem, while still making a unit with one very high stat not overpowering.
In any case, I'll take the following scale: 1-3 is neglectful, 4-7 is normal, 8-9 is devoted, and 10 represents lifelong training. Heroes could have things higher than 10.
E: Ran through some more examples, using some retooled min/max equations, and the squares of the stats as costs. Here they are:

I think that this is better, in terms of unit balance, but I'm disheartened by how increasing the lower stats seemed to come "for free," considering the overall cost. That said, the retooled equations are looking better and better. But maybe that's just the cold talking.
Aqizzar, you might be heartened to know that the # is one of the stats that I left up to unit type. The other one is Z.
