Buster,
This is comparatively speaking. She's more widely used than some planes in the stable for sure, but away from CV battles you don't see her nearly as often. Plane for plane, I see far more P-38s, 51s and 47s, Spits, La's, Hurricanes or N1K2s inland than I do F4Us (unless my whole squad is up) and frequently these seem to be D-Hog bomb trucks. But when I DO see an F4U I generally expect to be in for a tougher fight, because the guys who fly them away from the CVs are far more likely to be experienced sticks (granted there's exceptions).
