Charkov Campaign play balance Q

[Turner]

In the Charkov Grand Campaign played as PBEM, do you want the QFM for play balance or should that rule be left out?

Consider that all other realism rules are on:

Artillery Set Up
Recon Spotting
Virtual Supply Trucks
Low Vilibility Air Effects
Counterbattery Fire
Night Fatigue
Programmed Weather
Limited Air Recon

Should the QFM rule be used or not, to make it a balanced game? Disregarding historical accuracy for play balance. QFM could help balance it out if the Soviet forces are very strong (numerous), but I don't know if it's motivated in this campaign as I've not researched it much or looked at it in the game.
