Retek89: even taking Odahviing into account dragon mounts still aren't lore friendly cause the dragonborn need to get to only one place that he could not get to on his on, and Odahviing became a summon shout afterwards. For dragons to become mounts, they would have to be really underpowered cause a regular dragon would make the game too easy and unplayable. If made summonable like Arvak, they would still be overpowered and there is already a shout that summons a dragon to fight for you. Not to mention that the dragons are a proud and ruthless race that would never let a mere man or mere sit on his back like an animal unless the dragon was enslaved.
