If/when eyes or expressions are released, could we have a discount on them for, I dunno, 3 days after the release? This wasn't necessary for personal color changes because we have always had the option to chose our color when our knights were created. If the eyes are released, it will be the first time to get them ever. If they cost the same or more then color changes, many current players will not have access to them. This is what I think and why I think the changer should cost less for the first use sometime near the release of them.
There will probably not be a discount, but we will likely get a free set of the items.
