I could get behind this. I 100% agree that there is a really noticeable drop off in the Soviets' current effectiveness (without the use of soviet call in/doctrine tanks) if Axis is able to withstand the tide of light vehicles, and the T34 doesn't really have a defined role I would say.
The only real useful unit in tier 4 right now in 1v1 is the Katyusha, and even that is pretty situational since a lot of the current meta soviet commanders have some form of off map artillery, or ML-20s if you choose to go that route
maybe introduce a mechanic similar to the M4A3 Sherman where you can swap from AP to HE, but maybe scale back the damage some so the cost doesn't have to increase significantly as compensation. I know the sherman's HE shell power is viewed a bit controversially, but I think with proper damage tweaking it could put the T34/76 in a pretty nice spot.
Another option would be to make the 34/85, and I guess if they do it for the soviets they could add it for USF easy eight as well, a non-doctrine upgrade that can be researched either as a global upgrade at each factions' respective T4 building or perhaps similar to weapons upgrades on grenediers, however costing fuel instead of munitions.
Just some ideas.
Edit: made some parts less wordy so it is easier to understand
