Imo Grens should be removed or replaced by panzergrenadiers as mainline infantry for ostheer like in the first coh, although weak at first they should atleast be better than the current grens and they become better and get abilities to increase their utility as you tech up.
I thought axis are supposed to have superior elite infantry but lesser numbers than allied infantry but in its current state grens are just better conscripts but even conscripts now can kill 2 models of pgrens before losing and grens just don't have the numbers (and durability) to survive that long.
While a sound idea for a nostalgic fuck like me it would sadly require a huge overhaul of the Ostheer tech and not to mention reshuffle of the units.
The Panzer Elite pretty much had no other infantry apart from the Panzergrenadiers who were they're everything basically, besides team weapons of course. They also relied heavily on light vehicles and didn't have any good tanks apart from the Panther, I didn't really consider the Panzer IV F1 Stubby a proper tank.
