What is the general point of Champion Mastery?
I could understand if it was generally rather difficult to obtain but the reality is that all you really have to do is play a champion a lot and you level up.
It seems champion mastery is more an indicator of "time played" than "champion skill" and if that is the reality than I question why they bothered to name it Mastery.
Are people generally happy about that? Personally I hit a level and I'm like "oh, that thing"
I think a system that rewards players for playing well regularly would be better than just rewarding people for laying their favorite champs over and over.
