T2 is useless now, just Grenspam and StuG / Pz4 spam, then Conspam to T-34 spam will die like flies
Oh look its the CoH1 beta all over again....
I agree though, late game Russians are a bit broken atm. If they pull a fast T34 with a ton of conscripts, there's not a lot to counter them. The PanzerIV is decent, but since the Russians basically control the tech phase, it's not viable - it's a reaction not a prevention.
All they really need to do is buff the MP44 up to PGren/KCH levels, or make the T-34 cost a bit more fuel (i.e. what Basilone said). The Mp44 buff is the easiest counter though. It means that the Russians would need to invest more MP into higher-level infantry, instead of spamming cheap conscripts. This would delay the first T34, and also slow the rate of subsequent T34s. It would also make T2 actually useful; because right now it's not.
When the scoutcar's 20mm was actually a useful upgrade, it made sense to rush T2, get the shock scout car out there (It was possible at about 4-5min), and simply mop up conscript squads. Then they nerfed it to the ground. The flamer HT isn't good enough for the cost, the mortar HT is so situational its insane (and it's not the best doctrine anyway), and the PAK simply isn't effective enough vs. T34's, as it dies to conscript blobs within 2 seconds.
Currently my only solution is to be insanely over-aggressive. It works against 90% of the players, but if you run into anyone good, you just get shut down as they focus in on single squads that are capping. If they even maintain a 40% map control, the fuel income allows for them to start pumping T34s fairly early in the game (15 min? I think? Don't remember).
