Riot pls NEW Champ ban

Riot can u please ban new champions from Rank queues is really frustrating when a new champ is released and I'm minding my own business and and someone auto locks kindred (new champ at the time ) And we have to suffer for 20 mins ans that person feeds 1 /10 then in post game chat goes lol first time kindred its would be nice if you guy made them unavailable in ranked for the first 2 weeks (not definite time but a reasonable amount to pick up a champ) so people don't loose lp just because someone wants to try something new (thats what norms is for )where we have to use our ban pick to avoid it or not play ranked at all that or it really takes from the competitive environment
