Keep your rifles together in early game, with Kübel suppression gone you can be pretty aggressive in early game.
Except now you won't be facing said kubels, they'll be circumventing your troops capping and disconnecting your resources while you try to fight battles both in your rear (kubels) and in the front.
Kubels in this patch, played by people with experience, are by far the most OP element of OKW, denying allies resources and splitting their attention.
For those saying that this is makes up for the lack of suppression, i say BS. First there are 2 doctrinal choices that give OKW MGs, secondly, they are no longer handicapped by resources, so teching is no longer an issue and to top it off their base infantry has been buffed. Suppression is useful but by no means game breaking if you don't have it.
