Err... how can it drop if everyone is dropping with you?
Personally, I'm still trying to work out where the Con PPSh spam story came from... It seems to me it has originated after the patch was released, prior to that everyone was complaining about Shocks.
It will drop because you will be matched against players with similar ELO you've beaten before due to imbalances and now when the odds are a bit different it won't be that easy. Someone on this forum even complained that he's unable to win against people he didn't have problems before this patch.
As far as the second part of your question goes: I play both factions with Soviets being in favour and I can tell you and I am 100% sure with this that it was far easier to win as a Soviet last two patches before this one especially when you were good at executing some popular strats with Snipers, mass Conscripts or utilizing new commander. Experienced and done it myself for both sides of the equation.
And I never complained about Shocks. I found them easy to beat and later in to the game I was guaranteed free vehicles roaming time.
