Zygote, why would you even bring up the crosswinds thing? everything is affected by crosswinds, and I'd assume that lighter planes are more affected.
And not only would this have little impact on the game IMO, but since spits WERE based at rough fields, you can't really use the "well, they weren't ideally suited to it" argument. The Ju-88 wasn't idealy suited as a night fighter or strafer, but it was used in that role, with some success I might add.
