mmmhhh no ?
have u actually looked up the unit ?
it has very good pen on both rounds, fast fire rate, good AI and 0.75 moving acc
for the soviet this is a very good tank as it does not compete with the normal Sherman (?????????T34???????)
This tank is absolutely useless on the Soviet T4 roster.
You have the heavy duty TD on the SU85 and very good AT guns to keep enemy heavy armour away.
You have mobile rocket artillery that's absolutely lethal and must build.
You have mobile medium tanks that have great AI and can ram to guarantee critical tank kills.
A late game Soviet build looks like this: T70 in recon mode, 2 Zis guns, 1 SU85, 1 T34/76, 1 Katyusha. If you don't build as much infantry you have pop cap for more armour. The problem is you can't replace the 1 T34 because you rely on the ram to bring down 185-270 fuel vehicles, so your only choice is to pick lend lease, build less infantry and bring an extra M4C to the field. This however is pointless since you won't get much of a benefit from radio net. Building 3 M4Cs is not a good build.
