when we gonna make age requirement for ranked

tired of 12 year olds in my ranked game little children when their champs get banned cry and say they gonna feed and half the time they do even got a nunu mid with ghost cleanse building zeals running around inting. I don't understand even when I was 12 was never that immature every game ruined either some kids champ got banned or they just absolute trash zero brains. nonstop feeding see it all the time some kid feeding vs sum1 still building damage instead of buying armor or mr to farm not feed get carried . if u dint have common sense idc how gifted mechanically u are u shouldn't play ranked or be allowed to make a 15 and under ranked and 16 and older ranked I don't wanna play with any1 under 16 and that's being generous im sure some children I play with feeding and crying are probably still older than 15. riot making 9 new games cant even run this 1 properly no1 want to que up for ranked for 1 or 2 children to lsoe game for them I either get 4 human beings on my team and win or I get 1 or 2 feeders and they feed so hard cant carry waste of time its not skill just luck more often than not
