Winning games if you cant do a 1v5

No matter how many games I play, no matter how well I do, almost every game at least 1 lane completely feeds, and then people get mad and everyone feeds. I keep going positive in games, and having to just about solo carry against a whole enemy team that is fed. It is to the point where I want to quit League of Legends for a few years until they fix their idiotic ELO system, making it so no matter how well you do, you will loose. It defeats the purpose and point of playing the game. Even if you do really well, you are constantly punished for it, I mean, why play the game at all? This has gotten completely out of hand. after about 100 games, I finally gave up. Most of the games I played there was at least one person who completely fed. A few games of course I won quite easily because my whole game did well, but MAJORITY and a LARGE majority of games recently have been completely one sided too the point where playing is pointless. I`ll go positive and do so well, and then just completely loose because everyone on the enemy team is fed. What is the point? Riot please find some way to be able to fix this. All of my friends that play league have been saying how bad the current ELO system is, and I agree. I have been playing since Season 2 and I haven't seen a single improvement regarding good players getting rewarded for doing well ranked wise. I quit League just about a few years back due to this problem, and returned thinking it would be fixed, but it hasn't changed at all in almost 4 years.
