Only level 6 and 7 mastery in ranked
How would the community feel if riot implemented a system allowing you to only play champions you have a level 6 or 7 mastery on in a ranked game? I for one would love this idea because I main two roles and I have at least 2 level 7 mastery champs in each of them with multiple level 6 in case of a ban. Let's be realistic it doesn't take a lot to get to level 6, it's not that hard especially if you know your champ. One of my peeves is looking up on a site about my team and enemies and seeing a Azir that's played a whole total of 3 games on him.
Just a thought.
