If you ask me, the T-34 is too inaccurate. I know that the idea is to portray an untrained rookie crew, but the ingame tanks have such bad accuracy that it feels like the crew is not only untrained, but also drunk, drugged, and tired. The tank is missing 9 out of 10 shots against German armor at point blank range. That's right, the tank's turret is rammed into the tailpipe of a Stug, and still it fails to hit.
With the slow resource buildup of the Soviet faction, these tanks are already a HUGE investment with the available resources. Building them just isn't worth it, when I can use that manpower to spam out more infantry and AT guns.
