North, are you playing other game? TBH i think soviets op this patch and OKW... well it good to have 1 OKW for better artillery, at(yes, i think camo rakketens>paks in 4v4), repairs, cheaper mines and cp. Just watch LoH, nobody plays more than one OKW in 4v4.
Pumas, Panthers, Jagdpanzers, all come out very early for OKW if they convert. Jagdpanzers can come out earlier than a Sherman if a USF player like me builds all officers (like how it should be played).
It is idea of OKW, they can get first tanks really fast, but their second tanks comes lot later. Yes, they will have jp4 before your sherman if they decide to rush it, but by the time they can allow themselves 2nd jp4 (or other vehicle which makes more sense), you can have 3 additional shermans.
they aren't penalized enough for losing tanks.
Their tanks have insane scaling, losing vet 5 jp4 is equal to losing 3-4 jacksons. Even more - losing vet 0 jp4 is equal to losing all infantry, because from there on they would not be able to protect infantry from HE Shermans.
Jagdtigers
Useless, give me that elefant with command p4 on top of it.
King Tigers
Close to useless, su76 spam rapes it.
