Improving the Hextech System
I'd like to recommend a re-work to the loot box system. It's nice to receive keys for playing well and being sportsmanlike, but it would also be nice to receive loot boxes that I can actually open with those keys. This especially applies to players who only play ranked, and need to rely on the champions they have mastered, not those that would cost them LP. Not to mention, incentivizing every type of player is the key to longevity of a F2P online environment.
