Newly released champions should not be allowed in ranked until at least a month after
Getting sick of seeing newly released champs ruin people's ranked game. Either they don't know wtf they are doing at all and lose the game for either side of the team or they are blatantly overpowered that they destroy everyone and snowball. Usually it's the former.
It's the same concept as not being able to play champions that are on free rotation in ranked. If you do not have them and not practiced with them for some time you just won't be as good.
So playing a champ that was literally just released moments ago ruins everyone's game...
