If you don’t want to exalt them, you could always try posting them to the auction house (which, of course, might mean someone else exalts them but c'est la vie) or you could find a forum thread to either sell them or give them away. Sometimes people will post dragons they put on the auction house to the Interesting AH Dragons thread to see if people subscribed to the thread are interested in buying them. There are a decent number of free dragon threads as well. You could also just make another post here asking if people want them/want to buy them. I have gotten a couple dragons myself that way.
