Making old refer a friend skins available and exclusive with color changes.
The old refer a friend skins should be unlockable after completing the newest set of refer a friends.
However, the twist should be that every time a new set of refer a friend skins becomes available new colors for the old refer a friend skins also becomes available.
So if you were around for when the allo skin was red then you get to keep that color. But when the skin is made available again maybe the red color is now blue. So if I unlock it again I have both of those colors unlocked. And if I wasn’t around when the allo skin was red then I missed out on that color but not the chance to get that skin.
Then every time you guys add a new set of refer a friend skins you can just change the colors of all the old skins.
This way older players have that fun exclusive feel but new players don’t feel completely left out.
