Just pls dont sell more than 1 skin for a thing.
LoL is a bad example with selling all stuffs & uncertain upcoming skins policy within paid skins.
-level up > open skın
-use currency that can earnable in-game > open skın
-finalize Mastery levels > open skin
-buy one > open a skin
-join events > open skin
-update game > open skin
There should be just one way to get a skin with payment.. And one skin for a thing. Just update and make this paid skin better with a time, dont make new skin for same thing to sell. İf u want to give more, use other free ways.
-And dont even make free new skins for same thing before completing all similar cycle. Dont be like LoL. Pls.
