Panzergren combined arms provides +20% accuracy, movement speed, ability range and -20% received accuracy, it literally turns them from Conscripts into vet 2 Penal Battalions from the get go. If you don't utilize this feature then just stop playing DAK because you're playing this faction completely wrong.

I see it the other way around, a 300mp unit that is hampered from 1/3 of its stats until/unless you park a 260mp unit with low value around it.
So to rephrase it, DAK is having early powerspike, which on its own possible because enemy don't have counters to it. For me this is called struggling, because this is CoH2 all over again, where you are forced to play in one particular way in order to have your ground. And its not similar to a wehr situation, where other options are still alright, but Luft was just the strongest of them therefore always picked.
As for counters, idk, UKF can have IS+IS+rifle nades or Dingo+IS+rifle nades. Dingo is destroying 250 super hard and getting nades early isnt hurting UK economy over-all. While PGs under CA is a bit stronger, green to green cover its still a long stalemate. Not to mention that boys are bugged vs LVs right now.
The bonus range is quite large, you don't need to park your 250 on the frontline. But again why would you build a 260mp unit meant to fight if it isn't to use it on the frontline.
