We have been over this.
I view historical accuracy in this instance significantly less important than game balance and fun for both teams which helps player retention.
Have we? If team balance is this important I wonder why people did not complain about the load outs in former RO installments. Do you think that the IS2 if it was in the game should be balanced by throwing in the Tiger II?
If each team starts complaining about the advantages of the enemy without seeing their own we can argue forever.
I never complain about the MG42 as a Red Army soldier, it's part of the war, why go berserk on it?
The Allies have great weapons, not just the PPSh SMG. Look at the SVT40, you can part reload and do a full magazine swap, G41 can not.
The DP28 with its smaller pan magazine is ammo preserving and has formidable sights.
