So....wtf

Why is it when I someone going lethality jayce/lucian etc. and they get fed off one of my stupid teammates they continue to be toxic during the game, like legit, their using something thats proven to be overpowered and they think their good? imo we need harsher punishments in the report system....like 5 reports and your proven to have been toxic its a perma ban on that account, end of story, no warnings
