With the Season End comming closer and closer, people complain more and more about their teammates and that they feed. But let me ask you this:
Did you've won the laning phase?
If you answered no, then ask yourself if you really deserve higher ELO, since you are worse than the enemy.
If you answered yes, then you have a good KDA, haven't you? That means that your lane opponent died many times, right? Well, believe it or not, but your lane opponent is a so called 'feeder' too. If it was intentional or not, he fed you.
So the next time you complain about feeders in your team, keep in mind that the enemy got one aswell. You aren't on a disadvantage.
EDIT: Awesome how such a simple statement can create such controversy xD
