Anyone else tired of the game collapsing because of one idiot?

Riot really needs to sort this out. I can play with caution, infact, thats how I prefer to play League but there is ALWAYS some idiot in another lane that continually thinks he can win after already dying once before. What is this arrogant perception that people have, that they can win a fight they just lost.

"The definition of madness is doing the same thing over again and expecting a different result."

Yet Riot has done nothing to curb snowballing. I fail to see why the WHOLE enemy team should benefit from one person being an idiot. Snowballing essentially causes a bullying environment where one player is picked on and killed over and over again and gets abused by both the allied and enemy team over and over again. The whole allied team gets mad because they do not have any agency for the rest of the game because of ONE person and the person in question experiences the full force of League's bullying against then.

Yet Riot doesn't nothing to stop snowballing, to stop these kind of behaviours from happening. It just shows current League games to be a complete waste of time when YOU play as careful or well as you need to and then somebody else goes and feeds continually over and over again to the point where the enemy team is completely unfightable?

This is supposed to be "fun" is it. All Riot has done is built a community with the obsession of "getting fed" when what is needed is safer team play. This game hasn't been fun for almost two years and Riot has done nothing to stop the ridiculous amount of snowballing the game.
