Noone cared about the ability when it was in a shit commander, but now that its in a good commanfer its game breaking? I disagree with this train of thought.
Actually, no one cared about the ability even when it was on a good commander (the one with double t34/85s and IS2).
That's because until the last patch, most Soviet players absolutely had to play elite infantry (guards or shocks) to compete with upgunned grens and pgrens.
Now that conscripts can compete with German infantry, this ability is attracting attention. All that needs to happen here is a 15-30 muni cost increase for the PPSH upgrade and this conversation would be over.
