Its Relic incompitence again. In allied patch prior this they buffed allied stuff to deal better with axis in late game insisting that factions should be equal (read allies should beat axis in all stages).
Now they buff useless OKW early, mid and late game, which is fine, but they removed resourse penalty for no reason at all (why not ajust prices, ffs?) while allowing OKW to remain some mad late game things like jp4 veterancy and cp veterancy and mark target. OKW early game might be weak (however map pressense are not thanks to kubels), but OKW mid and late game now absoulte nuts.
Cp vet might be fine but 35muni old 50% mark target with accuraccy bonus on top of it is beyond broken.
I wouldn't say USF is any weaker than OKW in late game nowadays.
