For one, the FTUs are at max capacity; we cannot train b-coursers fast enough to meet what the CAF needs; so, there's only as many F-Xs as the FTUs can support. Secondly, I don't know the makeup of this class, but it's fairly likely there were at least a couple dudes who shouldn't being flying fighters, CAF shortage or not. For that reason alone, it was a good move to give the non-fighter aircraft option to ENJJPT. As far as getting "good deal heavies" that T-1 dudes "fight for," I honestly don't know what the right answer is.
