This issue should be raised everytime there is a new champion release, because for some reason, more recently I have been queued up with people who have just 2 or 3 games on new champions. IT'S NOT ENOUGH. I have asked this before, Why is it so hard for riot to put a requirement on champion mastery level for ranked games? I mean surely you haven't even scratched the surface of a champion in 2 or 3 games, which I can guarantee 1 of them was most probably a bot game. At least playing a champion to get a level 3 or even level 2 needs a few games, to get used to the champion against different mactchups.
It can't be that difficult to demotivate people from inting in ranked games with new champions, can it?
