50% is too much.
JLI only has one scoped rifle which 45 cost munition for upgrading. Pathfinder has two scoped rifles which are free, but hit critical at 40% HP.
Keep in mind JLIs critical hit at 70% HP per model and their sniper rifle is more accurate. Brits and usf infantry are even more expensive than volks as well.
Jäger should be CP1.
Assault Engeneers 5th man arrives too early. Their flamer in comparison with new tech-system is kind of problematic. Now it should be looked behind something, Ostheer has real trouble versus such early flamers
+ mortar combo.
Bulldozer has a turret and force 4men Ostheer troops. That is reason enough to show up, that same stats as Brummbär's weapon is no good idea. It should perform worse than actually. OR the artillery ability of commander has to be replaced.
I already said that vet0 5 man assault engineers are a bit much IMO and I actually try to stay away from using them right now. If they got the 5th man at vet1-2 I think it'd be much more balanced (as I already said). Also, pios get (nondoctrinal) flamers just as early and can be 5 men with german infantry doctrine, while also being significantly cheaper and backed up by an objectively better mortar, so I don't see any inherent problem here except assault engineers.
Brummbar faces 4 man brit squads. Bulldozer faces 5 man okw squads. That argument hasn't held up since WFA and brits came out. And again, brummbar still is more armored and has more health and has a barrage at vet1. I don't see a problem there either.
