Manpower increases aren't the answer.
The solution to the manpower problem is to eliminate colonial manpower counting towards national manpower and to increase the risks of using dissident minorities in your armies.
This would serve to control Austria and England's army.
The solution to limiting armies like the US, Italy, and France is to just increase costs. I still think divisions should cost between 5 and 10x as much. But the AI needs fixing for that kind of mod to work. Whenever I try that now, they don't care much about the increased cost and never build modern ships, which is a major peeve of mine.
