AKcurly,
I think the changes in vehicle armor due in v1.07 will make Panzers pretty well immune to 20mm fire, regardless of the gun type.
I don't know if the Osti will be more vulnerable to 50s and German/Russian/Japanese 20mms, but I sure hope so.
I agree that these changes would make the F4U-1Cs/Typhoons/Spitfires less of a requirement for base capturing.
