I havent played long enough to know if this is end game content.. But, man would I love to be able to fly a dragon around skyrim. thinking of WoW got me thinking this. How cool would flying mounts be? May not be Lore-appropriate, but it would be so nice to just fly around and take in the scenery. I'm sure I'll get some, "This isn't World of Warcraft" replies but w/e. I dont want it to be WoW. A game with this nice of scenery, I'm sure, would be enjoyable from the air as well.
I dunno, just a thought.
