They could totally make a system like (as an example) 3500+250 per level 50 combat class for maximum and 400+25 per level 50 combat class for maximum. This would end with 9 (ninja) for 5750 and 625 total soldiery per week.

I mean, this would make a semi-balance since if you don't have that many classes, no real need for a lot of soldieries, but if you have a lot of classes, you need more to work on all of them.

just my thought.
