Against Pz.4 it is good and ZiS-3 but its does not cost 130 fuel. And to spend 130 fuel for a Pz.4 hunter whose main cannon only scratches the infantry (machine guns do more damage than a gun) oh no buddy, I don't see any benefit here. The T-34-85 is a slightly less useless T-34-76. If the T-34-76 is useful as a kamikaze unit. That T-34-85 at least can kill Pz.4. 1st veterancy and the absence of any real abilities further aggravates their situation.
while i agree the T-34-76 is a really bad unit outside of ram kamikaze i do think the T-34-85 is the best medium tank in the game
1. it has more hp than all other mediums soo it can reliably tank an extra shot which would kill any other medium... this scales even more with veterancy as it means the tank is much more difficult to kill and subsequently easier to accumulate veterancy without attrition... the tank also gets some massive veterancy bonuses which helps scale its performance even further...
2. it has massive DPS with veterancy... its ROF with veterancy is almost doubled... other tanks get like 30%-40% boost...
3. it has the highest penetration of the mediums soo it can reliably dish out such damage
