Hmn looking at the monstrous number of conscripts after a few days of play, and even a small expansion. I think the limit function of these units can help.
The reason is the cost of maintaining them. It is only 15 units of each raw material, but with their number it increases to astronomical numbers.
I propose 3 variants.
1. Limit X per province in your possession.
2. Limit set by the player. With minimum and maximum. That someone would not use the fact of their absence.
3. or two variants together.
in addition, management becomes terrible for such a quantity
