Whenever we make a skin we’re faced with a lot of difficult choices. Not only what thematic world we want to visit but also what champion to make it for.
There are some champions that have much smaller audiences than others. This means that some skins don’t do as good or a job of “paying the bills” as others.
This all being said, we don’t always choose to min-max for revenue, which is why you skins being made for lower play rate champs like Papercraft Anivia or Darkstar Shaco.
One active effort we do have though, is we’re trying to augment our skins and content pipeline through a variety of means. This is both having more people work on League content but also looking at our tools and processes and trying to find more effective ways of working. The end result, we hope, is that we can create more skins for lower play rate champs per year.
