The idea behind peasant levies is that your army is composed of untrained mobs of levied soldiers, rather than few well trained units. However, in practice peasant levies make you not have an army at all.
This is because Peasant Levies gives a 0.1x modifier to POPs becoming officers unless they are aristocrats (I'm guessing to represent nobles leading armies). This however completely prevents you from recruiting any units as aristrocats have no reason to convert to officers as they make more money working in Manor Houses. Since you can't recruit officers, you can't recruit soldiers either. My current army has shrunk by 1/3rd in just 6 years because I have no possibility to replace battlefield losses.
You might be asking why I haven't just switched to Professional Army (which seems to be the meta to do as the first thing as any country). My main reason is RP, I'm trying to make a country heavily controlled by aristocrats. The fact that you basically want to switch to Professional Army as soon as possible whenever you play tells me how broken Peasant Levies are.
To fix the issue I would remove the 0.1x modifier for qualifications completely. Peasant Levies already lock you to only using irregulars as your conscripts, which is a big nerf to begin with as soon technology progresses even a little bit.
