It's not that allied infantery vets quicker, but they got only 3 vetand they are elite while okw needs two more vets and you get experience when a model dies in the squad, bigger = more experience
Pazerfuzilier don't need a buff to scale to late game, they come early so you can make them vet 5, same for Falls, i thinked about something like if you deploy falls not in a building they are 50 MP cheaper (apply this to all units spawning into buildings )
Sturm offizer don't need to be touched, it's a risk you take, you need to assume the consequence
MG34 need a buff so badly
