I like it that this doctrine has a single T-34/85 call in, it adds to the versatility of it. Besides the multipurpose use of cons, you now get one decent tank that has a reasonable chance vs Ostheer Panzer. Giving this doctrine 2 T-34/85's would be a bit overkill I think, perhaps make them a tad more expensive or something like that?
Well radio intercepts, ppsh, conscript repair are all no brainer abilities that you will choose in almost every given situation. Having Soviet player have a katyusha or su85 on the field then rounding off their army composition with a single t34/85 is honestly scary. T3 and T4 Soviets is so effective when used in combination with one another in 1v1.
There is currently no risk in choosing this commander. I believe if you want to get out t34/85's to complement your T4 there should be some risk involved with having to float resources. This doctrine can give you an early game advantage that just keeps on smashing on the pressure with t34/85 and light strafe.
