Scales don't need its own color pallet, cmon now.
Currently this race has the most customization options, there is no reason to tack more onto it. There is already little reason for players to stay their current race it also doesn't help that races don't receive race new exclusive customization options.
Horn size sliders? Probably. Some of the horns are pretty dam big to the point where its difficult to see your face.
Horns attached to hair isn't a problem. The horns probably grow and are groomed similar to the hair. I thought that was kinda obvious.
