Soviet have access to more doctrinal units in more commander than any other faction. The power level of these unit is above average and so is there cost efficiency. The "old design" come with certain perks.
That is because they were initially only allowed half their unit roster at one time and their Commander was to fill in the gaps. Even then, Ostheer has a larger number of Doctrine units than Soviet does, mostly offering expanded options ontop of their core units as opposed to Soviet's offering superior supplements to inferior core units. Ostheer doesn't
need a Tiger or Elefant when such roles can be handled in another manner by a Sturmpanzer or Panther, but Soviet's may need the IS-2 because they have no stock breakthrough unit. OKW doesn't need Panzerfusiliers or Fallschirmjager when they Volksgrenadiers and Obersoldaten, but Soviet's might need Shock Troops or Airborne Guards because Conscripts and Penals cannot do those jobs.
There is little indication that the Soviet faction is actually weaker the Ostheer/OKW. The only trouble it had so far was against osttruppen possibly even vs 5 men grenadiers and those doctrines are being nerf.
The indication would be pick-rates and win-rates, which are lower than others.
T-34/76 was meant to be a flanker tank and that is why it penetration is increased with range more than other units.
If that is the case, then it is terribly equipped for it's job, inferior to even the better armored Panzer IV at flanking, due to the latter having Blitz. Base mobility is only marginally better than the Panzer IV or Sherman, and marginally worse than the Panther, which also has Blitz. I cannot see the Cromwell stats because it's broken on the website, but the British Forces Unit Guide says it's comparable to the M10, which is superior to all Medium Tanks, ontop of this it has Emergency War Speed.
Conclusion: The T-34's mobility is average and penetration is poor, which doesn't make it particularly good at flanking because it doesn't really move faster than other tanks and it cannot reliably penetrate the rear armor of a heavy tank as well as any other medium tank.
Once more it there in patch notes in black and white.
"The intent isn’t for a full health T34 to ram other vehicles; instead, ram should be used when the T34 is near death to highlight its usage as a last resort type ability."
He is very clearly talking about Ram's original intent, which is at odds with what the current team believes it should be for.
