Iksar's sure do, Kerra and Ratonga have had extra skins since launch, and they have shown multiple skins in different screenshots in and out of time.
Go to an Iksar on Eq2players who hasnt paid for the players addition, it shows a zebra striped Iksar as a placeholder image.
If you buy a painting in EQ2 and put it in your home, it shows a female iksar with what seems to be a form of our old scale patterns from EQ1. (but it is an EQ2 screen)
Please give us our scale patterns when 16 goes live, please?
