About the upcoming key and chest system

I love what you are doing with it giving us the opertunity for free content, but I have a request can you work on also adding a master grade to other game modes when not ranking or playing with friend I enjoy Arams the most. From the phasing in the overview of season 6 it looks like it won't be implemented till later in the season I request that you try to have both the grading on other games mode and reward system both in place.
