He´s actually right. The T-34/85 devastates infantry, while the Panther is more of a special purpose tank. If you see a Panther finishing full health squads with one to two shots, you would have a point. Arguably the Panther is a heavy tank, being in the weight range of the IS-2 with 45 tons.
"Underperforming" ISU-152s... now that´s what I call "toplel". You are aware that it handles any tank easily and only struggles versus Elefant and Jagdtiger (again, specialized vehicles which suck versus infantry).
It looks more like Soviet players want to totally own German armor with their own armor. Most Soviet players just can´t handle the fact Germans get better tanks. Guess what? They did...

In 1939-1940 Russia was making T-34/1940s and KV-1/2s while Germany only had Panzer IIs and Panzer IIIs with short barreld guns.
German early war tanks had such poor characteristics but where solid and reliable machines with radios, but Soviet eraly war armor had way superior armor and guns while they were unreliable and such.
If you want history then expect fighting KV-2s with your Panzer IIs, but ofc the tide would turn late game when Germans stepped up significantly, but dont pull the "Russia had worse tanks" card, they had amazingly powerfull machines in the early war that German tank crews feared.
