Before attacking France try clearin the sea zones out of transports, english units then would be destroyed. Destroying rail lines before attacking also helps, but that's four hits, hard to achieve leaving aside AA and air units. I think in AWD Deluxe France is too strong and as you said her counter attack can be painful for Germany.
