Don't know if this is something the Devs would consider adding but it would be nice to have an option for Mordred to have permanent draconic features ranging from Draconic Eyes, Partial Scales, Fangs, Tail, Talons and Wings. And you could either have only a few or all of them. Could be used as a sign for certain Dragon Riders as a way to showcase their deep connection with Dragons while people of the Pendragon bloodlines or whose bloodlines are strong enough to have more features. They could also make it where they are able to hide certain features if they want to for whatever reasons though if it was me, I wouldn't hide any of them.
