Tiny Rewards for Positive Players
Every [x amount of time (perhaps every fourth patch (~8 weeks) or so?)] of not receiving any punishment or ban (this includes things such as LPQ and others), players will get a random small reward. It could either be like a "Spin the Wheel" thing where you have a chance to get various prizes (Gemstone (10% Chance), Hextech Chest (20%), Hextech Key (20%), Premium Chest (10%), Key Fragment (30%), Random Champion/Skin Shard (10%), etc.) or it can be a rotating reward similar to how the rotating gamemode queue works. This doesn't have to be an actual thing, it's just to help Riot get some small ideas to give periodically to the positive players of the community rather than their annual mystery skin or mystery champion.
