Rank - Champion Mastery Level
At this moment of League players have been flaming each other for not being able to play good with a champion they pick in ranked, sometimes it's just a bad game but others it is just that players do not have any excpirience with that champion, so i would recommend a new system that will allow you to pick a champion in ranked only if you have enough excpirience with him, and the only way you can see that is the mastery levels, so maybe if you have your mastery level on a champion up to 4 or something you can choose him for rank, but if not you have to get excpirience from normals with this champion and then go with him on ranked. This is the first time i am writing on Boards and sorry if i have some mistakes in English. <3
