1.Panzerwerfer is OP and also pins, but katyusha barely does damage and fires very slowly, also the katyusha doesn't pin and costs practically the same.
2.OKW gets free flame nades, Soviets have to research the slow-throwing molotov
3.Wehrmacht gets free panzerfaust, Soviets have to research AT nades and riflemen have to wait until vet 1
4. T-34/76 is in the same tier as panther, seriously?
5.OKW can build all their armor in their second halftrack deployment, Wehr has to research, Soviets have to build all the vay for their weak tanks, Brits also need a lot of teching. And no other faction's Tank-producing building can lock down a teritory and serve as AA.
6.Panzerfusiliers are the only 6-man squad besides ostruppen, but they become elite infantry once they get G43. Also AT rifle nades.
7.Wehr sniper has the same HP as Soviet sniper, which is a two man squad. Soviet snnipers are just a MP sink, worse accuracy, and very weak.
8.Conscripts are the only infantry without a non doctrinal weapon. They are useless in late game because of this.
T1 is the cost for panzerfaust. OKW is getting side-teching costs soon and I dont know whats up with the rifleman AT Nade vet 1 thing, relic vigorously said they wont change it. The Katyusha and Panzerwerfer thing is an asymmetrical thing or something like that. Those other stuff are not issues except conscripts and the wehr sniper thing you mentioned.
