Flying is useful but doesn't increase unit's killing power to much, but etherealness rules on almost anything, especially in the early game.

Flying raiding groups supported by raiding mages can be very powerful, but I guess that will be balanced by the nation's poor PD. I'd think that the PD having mostly unarmoured humans and some cavalry, while 20+ could have horse archers and camels.

It seems like the flying carpets could continue the theme of flying elite units in later eras, perhaps starting with multiple fliers/carpet like those Arcos chariot archers.
