Minimum mastery to use a champ in ranked?
I'm not sure why some kind of system to ensure that people know how to play a champ (not that mastery is the best but the best trackable variable I can think of) in ranked. Seems like so many games are thrown or people rage when they play a champ they don't know in ranked get stomped by there laner and then afk or are so tilted it might as well be 4 v 5. Ive found going over games where a lane gets hard stomped a majority of it are people new to the champ and not knowing how to play it.
Should there not be some minimum mastery level on a champ to unlock it in ranked to ensure they know at least the basics of the champion?
