That is a damn feeding and inting feast in low plat where should have people atleast a decent sense of their champions, game play and how to do the simple things like not feeding.

Everyone feed and i suppose somehow magically to carry ADC which is btw, mid lane that doesn't know that destroy and he can't play it save while jungler just making the mistake of helping mid and bot which made him goes on giving free kills streak.

Tell me how someone should be able to hold himself for not afking in such match when your team is 1-6+ atleast while not wanting to ff at all wasting your time and making you more raged and tilted.

Tell me why people that get toxic and goes afk cause of such feeding actions from their teammates get banned while the people that goes in like 3 games atleast with negative KDA not getting banned or not allowed to rank for while or atleast get hard demoted down to division that fit their poor gameplay ?

You know what, i will tell you a little thing that can solve the problem of toxic players, the people who get carried and who get lucky teammates to carry them to high elo. It's making your gained/lost LP count with your KDA and your champion performance in grades meaning people who lose and still got a decent CS/KDA should lose less LP while people who get free win with poor KDA/CS should get less LP.

It that simple to balance all of that and make sure that people belong in their division if you don't want to banned them for playing badly.
