People shouldn't be allow to play champions they never played in ranked
At this point, after the mastery system had been out for so long, when someone plays a chanp they have no mastery level on, it basiclly tells you the player either: 1.doesn't play the champion enough to actually know the champion. 2. is a newbie.
both of which really hurts the chance of the team winning.
Maybe mastery lv3 is a decent limit? that is like what? 10 wins?
