1. Relief Infantry being replaced by Osttruppen or an Osttruppen based squad. Currently the ability goes against the game's philosophy of trying to preserve your units.
2. Forward Retreat point of some sort in a doctrine, I don't really care how at this point, like the 251 having it, or a bunker/forward HQ, as long as they have it because it's a pain playing without one on a big map if you got infantry heavy. That's also the reason I go tank heavy with the Ost so I don't have to retreat my infantry all the way across half the map.
3. Additional repair options, I mean I like how they're trying to buff Ost's repairs but they're still currently the most limited out of all Armies in terms of repair options, out of their about 20 doctrines only about what, less than 5 have repairs options?
Meanwhile every 2nd or 3rd Soviet and UKF commander has crew repairs or something else.
Something like a repair station upgrade for their bunkers or a mobile repair and recovery vehicle like the 251 would be nice in more doctrines.
4. Speaking of Halftracks, the 250 should be standardized in my opinion.
No more battlegroup call-ins or mortar HTs, you get the ability to build an un-armed 250 in your mechanized building and from there you could upgrade it with an MG, a Mortar or turn it into a mobile ambulance. Would make the vehicle much more useful, unique and versatile instead of having 4 different versions of it across multiple commanders.
5. Fallschirmjägers in one of the Luftwaffe doctrines, I think they fit and they should be given a proper doctrine of their own but I guess shoving them in one of the 2 already existing commanders also works.
Here's one of my suggestions of a Luftwaffe Supply doctrine rework that includes them:
6. King Tiger in Mobile Defense doctrine. After the severe nerfs to the Osttruppen reserves, later Puma and now the Command Panzer IV the doctrine that was once viewed as the savor of the Ost has really been reduced to being pretty much absolutely useless and obsolete. So in my opinion giving it the KT might actually be a saving grace for it, maybe as a replacement for the Command Panzer IV?
That's just my own personal opinion of course.
