The +4 defense can be attributed to combination of being able to fly, of have extra brid like agility, and having gone through extensive training on how to make use of their agility and do hit and run tactics. Other flyers simpl;y woudn't have that same agility and training.

I see caelum ifantry as being very good at staying out of harms way until they see a momment to strike. I don't see units like draconians, angels or devils doing that.
