Been talking with my kids about new dragon types:
Turtle Dragon is the biggest one we think is missing.
Dont remember seeing a Panda Dragon in the list anywhere either.
As you have Orcs, Elves, Dark Elves, etc, why not go with Goblin and Ogre Dragons (if they aren't already)
Apologies if they are already there, but I dont remember seeing them in the list.
Thats all for now. :)
