Blocking summoners with little/no experience with a champ playing that champ in ranked games
So i just finished a ranked game that i lost due to a Brand that fed his laner. Now i understand that everyone has bad games sometimes and im far from being a top player, but when me and others members of my team asked him to play safe he responded; "NOT MY FAULT I NEED TO LEARN HIM".
To stop this happening in general, I think riot should use the champion mastery system to block people with a master level below 3 from playing ranked games with said champ.
This is my first post so if I have missed anything or a post along the same lines already exists please ignore :D
Thanks
