Ranked Reward Idea: Chroma Based On Ranked
So when the ranked season ended, you get a single token based on your ranked; eg: a bronze token, silver token, gold, etc.
You can combine this token and any champion shard or champion permanent you already own in Hextech crafting. The complete result would be a chroma on that champion's base skin that is the colour theme of your rank.
So if you combined a diamond token with a malphite shard, you get a diamond-looking malphite. Or if you combine a silver token with a braum shard, you get a silvery-looking braum.
