The Dragon chest scale fix is going to take some time as it's not only textures, but voodoo in the definitions of the client that has to be performed as well as getting blessings from Vi to add the missing intensities of the throat scale textures to the client... Which is problematic because someone, somewhere, won't like the change to their six year old ancient with the missing throat scales and now that the textures are fixed, they'll be leaving the game because of it...
As soon as the smoke clears a bit from the tier2 revamp, I'll ask around and see if there's any interest in my fixing a few sticky Dragon bits... That one head with the missing neck piece (the one you can see through in the character creator) has bugged me for years... And I have a mad desire to put the proper head on the Khutit model...
