In this meta its really hard to turn around games.

But on the other side of that.. . . You then shouldnt be complaining that it doesnt matter what you do when you get fed. You may not be able to beat every other fed person if all your other lanes fed but you can then just not group up and split push. But realize that that satisfying feeling that you get from being able to snowball your enemies can also have that type of gameplay and feeling. Players like to cry as if only their feelings matter. If you regularly cant win games early or your allies cant why not try to stall out so that all the come back mechanics riot put in the game can benifit your team. More often than not people pick late game champions versus early game champions then surrender because they lost early.
