Dragons atm are not a playable race meerly merc's. As for your comments on Dragons, just have a look at the size of their cranium and compair it to a humans, much larger. And consider we only use what 10% of our brain any who im sure there is reasonable excuse to evolve around this, look at how smart dragons are in tales/book/movies that there some kind of higher being looking to protect us and the inferior species.
