Proof that you can solo carry

Hello, the reason I made this is because a lot of people in my elo complain about not being able to rise due to their teams dragging them down, well here is proof that you can 100% solo carry your team. http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1848619457/210616440?tab=overview although irelia finished 9/6 the last 3 kills she got near the very end of the game. Basically every lane was losing, their jungler was out jungling our junger, bot lane was getting camped and feeding, and I was getting camped aswell, irelia got a kill on garen, but he killed her twice after that and made a comeback. Instead of flaming my team, I focused on myself, won my lane, roamed bot around 7 times and got myself fed. I instructed my team on what to do, most of the time they listened but janna and irelia 2v5 tower dived and died when i pinged them back. But I kept a cool head, and eventually led my team to victory. (though i was playing Lebroken cause the mothertruckin' enemy midlaner FIRST PICKED MY YASUO!)
