ngl I find it easy to kill
100% this belongs in the game, either as a premium or foldered with the T-44-100.
The MS is arguably the ultimate variant of T-44, I think it should be given access to the HEAT round but it should be 7.3, definitely not under 7.0. If it didn’t get the HEAT round it definitely belongs at 7.0
It would be quite mobile with the upgraded T-54 drivetrain and it would be stabilized, it definitely would be a beast and provide a significantly different gameplay experience compared to most of the USSR lineup at this BR.
If given HEAT-FS it would probably be way closer to 8.0 as it would have a bit worse forward speed with way worse reverse speed in comparison to Object 906 but with way better armour. Furthermore the HEAT-FS round would be very similar in performance given that it would be the same as on the Type 62.
So in my opinion it would be more interesting to play a stabilised medium at 7.0 with great mobility, good to very good armor but with a weak gun rather than another HEAT slinging “light” tank around 8.0.
