rank ban idiots that cant find team builder

because instead of wasting 20 min of my time with vayne mid and another shitty loss due to toxic retards in your game i wouldnt be stuck in low elo on one account and winning in high diamond on another. Only plays vayne trolls if he doesnt get adc and still is terrible at it. Why should i suffer because this douche bag just forces his way and basically intentionally loses? Just rank ban the 1 trick trollers forever and force them to team builder holy shit toxicity went down 90% no way?
