Finally one last comment. As Ed reviews his released games (1914 & Squad Battles) and provides updates, so do I.
The Variant 1 scenarios for Kharkov '43 were introduced (ironically with a lot of the items learned from Moscow '42) to stop the ahistorical early counterattack by the German Panzers. The community are the best play testers we have and if items are found that unbalance games or provide forces that were not available then they will be corrected.
As an example of unbalancing a game it was found that blowing bridges on rivers was all the German player had to do stop the Soviets advancing on Kharkov. This resulted in wired bridges being introduced. The early counterattacks by the Panzer was mitigated by reducing their starting strengths so that they were compelled to hold rather than launching premature attacks - this again moved the game closer to the historical record.
So with this in mind, please do provide your feedback, but make certain you have played out your strategy versus a human player and you can demonstrate why this solution was not historically possible. You might be surprised how many ways your opponent finds to take advantages in the flaws in your 'clever' strategy!!
