D) We didn't really have much time with actual Dragon Knights, did we? We had 5 minutes with Talana, 10 minutes with Lovis the imprisoned spirit, 5 minutes with the imprisoned and angry Amdusias, and the rest of the game was with Ygerna who was impersonating a Dragon Knight.
Fair enough. But from what little I remember of the lore, Dragon Knights were something of a separate, powerful ruling class lording it all over the little people (which, granted, doesn't make them inhuman) and people started thinking of them as actual dragons because the real dragons just kind of faded away and disappeared.
Plus, in Divinity 2, I believe you already had the option to define yourself as a Dragon Knight. Which you could compare to a person transforming into a wolf under the full moon defining themselves primarily as a werewolf rather than a human with a cursed power. If you get my meaning.
Finally, when people talk to you, the Dragon Knight, they seem to put particular emphasis on the Dragon part and not so much the Knight part. There is at least one NPCs in Flames of Vengeance who comments on your hot, sulphurous breath. Even if the Dragon Knights do not actually have such a breath in their human form, it still means the Knight is considered more dragon than human.
So if the Dragon Knight(s) consider themselves a dragon and everybody else considers them to be dragons, it could be argued that they are dragons (sort of). Yes, they start out human, but then again, so do vampires.
So, you know, the Dragon Knights may be ruling lords and all that, but it's difficult to see them as representatives of the human population. To me, anyway.
EDIT: Also, my opinion may be somewhat influenced by the fact that I'm tired of playing as humans in fantasy games and am therefore more prone to viewing Dragon Knights as an interesting fantasy race that simply aren't that human.
