I agree in principle but not with the solutions.
Let's look at the "light" AT options for both -
Soviets - Guards, Partisans, M42 light AT gun
Ostheer - AP rounds on the MG42, Upgunned SC..?
Solution - give them doctrinal light AT support to delay/soft counter the T70
Soviets have many things to deal with the FHT so Ostheer should have some kind of soft counter to the T70 (preferably infantry related).
Or perhaps even increase the effective-ness of the upgun, with a cost increase.
I also think panzerfausts should do more damage but not cause engine criticals but that's another matter...
