Yeah, I have seen that, and supported it and want it so much, because it would be, at least it seems like it would be, a low effort way to bring out new variety in genes, and give players the ability to further make their dragons look 'unique' while still having the same 'gene'.

I think the biggest variant issue would be for iri/shim because it is drawn by hand, so they would have to do all variants by hand.

But, most others would be minor changes, such as colors, which they have a program to do for them, or removing a layer or 'cutting' out a bit of the gene (such as runes' feet)

I *really* really wish they would bring that out...
