I believe this belongs in Game Opinions and Ideas, just sayin'.
Also, there are beak items in item packs which may help for griffins so griffins I don't think are much of a need, but canine manes such as small ones like a mane Chasanapatab has (a character of mine) would be great. Wolves do have tuft-y areas that seem like manes to me, so I like the idea in a way.
