In my mind..... the carry is a myth.

Teamwork in general is much more important and will help you win. Getting a lot of kills is nice by carrying but carrying depends on other team not only being just as bad as you are. It also is based on that enemy team not working as a team either and let me tell you from the games I have played the enemy team is usually better and more organized. So, even in game where I get a bunch of kills, which happens, carrying wouldn't help me win more. Having a working team who wants to play as a team would help even more.
