Check the memoir of top ETO Allied ace Johnny Johnson, "Wing Leader"..
He used the term 'rabble'..to describe the VVS units he encountered..
The LW were capable of putting up organised air-combat sorties - limited of course - in scale,
though - by comparison to the Allies massive available strength.
Still the LW were flying ( largely) technically competent & organised ops, albeit affected by the realities of war situation - which obviously caused logistic difficulties plus the severe pressure from
attacks on their airfields , infrastructure, & sheer numbers of allied planes in the air..
But they were flying, fighting & claiming victories against the Allies - right to the final days of the war, with remarkably creditable effort, considering..
& AFAIK, that 'do not engage' order to the Jagdwaffe - is just another propaganda myth..
From memory - the VVS only accounted for ~15% of LW A2A losses..
& the LW ratio of victory-to-loss on the Eastern front was always higher too..
