I got like 40 keys and 0 boxes.
And I haven't gotten a box in months. I have a relatively small champion pool, and I think you need to increase champion mastery to get boxes. So basically, if I max out mastery on every champ I'll stop getting boxes??? So the box system has a limit to how much you can get for free? Seriously?
P.S. Keys are gotten from playing champs you're already mastered then cause I get a lot of those. Well at least keys are getting an alternate method for those that have a lot of boxes, but what about us people with no boxes???
