The T-34 has had a large damage and small penetration buff. The SU-85 has not had its damage or penetration reduced. T34-85 has been unchanged (but still needs a buff). IS-2 has been improved. There's not been any nerf of Russian AT options at all.
su 85 had its speed reduced to the point it cant chase a p4 reliably, double it if you go for the focused looking ability, t34/76 are not reliable. even their ram is not a sure gun damage (i understand that you have a possibility of engine damage. but to me gun damage should be 100% of the times. that's it those are the options soviets have vs tanks. not counting the at gun, what are you going to suggest, to reduce my commander options? because you need doctrinal tanks to beat non doctrinal tanks?
to stay in topic. i think this is caused by German wining. and them being the majority.
