Reduce the effectiveness of Ram against heavy tanks (especially full health ones) and increase penetration of the SU-76..?What do those 2 have to do with anything. They are in different tiers, so you would never see them together anyway.
A lot of people just aren't getting that unless you choose a doctrine with call-ins this is the best tank the soviet player is going to have. Take away ram and they are completely unable to take on panthers and tigers, let alone elephants, and teching to get su-85 isn't really feasable as it takes about 200 fuel and A LOT of time to even get out a single SU-85. Until T3 is capable of taking on heavier tanks without ram it is not going anywhere.
