Sometimes you have to take responsibility for your actions. I will admit that sometimes I am at fault and will face the music for my actions.
Part of the problem was the fact that I was smurfing, but having three games in a row that a person on my team quits, leaves, or AFKs is just too fun of a dataset to ignore!
The oldest game was the Sion one. I had called mid, but then Katarina called mid. She wasn’t willing to play any other lane. Even Wu Kong on my team said “Kat’s a better mid” and I just ignored them. Kat quit and never left spawn. I told that Wu Kong “this won’t be the first 4v5 that I’ve won.” That poor Lux. It was possibly my fault that Kat wouldn’t play with us because I was the one who wouldn’t let her mid.
The next game I played as Kog’Maw and our 5th player didn’t quit until he tried to invade the enemy red at level five and get surrounded by three people, who he mocked in all-chat, then they killed him and he quit. I’ve already written about this game, so I won’t go into any more detail. Shaco was probably angry that I didn’t kill the three people chasing him through the enemy jungle. Yup, my bad.
The latest game was when our Master Yi refused to tell me where he was going in Champion Select. I ended up as “support” Nidalee with Vayne. Ya, I can boost her attack speed! This should work well! However, when I picked up First Blood on Jax, and then finished off Riven and Fiddle in our lane to start the game 3-0 Vayne said “ff you nid i quit” and she literally quit the game. My team mates were pretty ecstatic; it’s one thing to cause someone to rage quit on the other team, but getting someone to quit on your own team while you keep them alive now that takes talent. I used my heal on her to save her from Riven and accidentally picked that kill up with an auto. There’s not much else level three Nidalee can do when someone is diving through creeps. I guess I did something wrote auto attacking the champion who was diving my AD carry.
In all three of these games I went on to have the most kills and my team won. So Rendow, EatDatP00poo, and Dabronie, go die in a fire. You’re useless, I don’t need you, and I hope your accounts get banned.

The only thing worse than someone rage quitting is when the person who rage quit is a friend of yours that you queued up with. Especially over something stupid like getting first blooded. On another note, I’m surprised you won the 4v5’s with the games being so long. Whenever I’m down one I always try to win as quickly as possible so their whole team can’t get max level and items.
I actually just had a Xin Zhao game fall off my match history that was also a 4v5 victory. I don’t remember why the person quit, but I had an AD Blitz, and useless Kat, and a Galio that I was on Skype with. I wasn’t having any problems early game, but just like you said, when the game went late I couldn’t fight Garen, Kha’Zix, and Riven, while running through Anivia ultimate/walls, and still win.
My Galio was being played by my cousin, Brent, who is fairly new to the game, and was even more back then. His play at the end of that game won it for us. Him and I were being chased out of the enemy base and so I told him, “When I give the signal turn around the just press R.” The enemy team had caught up to him, but were ignoring him because they wanted Xin dead. If Xin dies, they can win the game. I give the signal and Brent turns. He’s wading through three enemy champions and all three ignore him entirely. When he pressed R I turned and went crazy. I had a triple kill before his ult finished and the “GG”s starting rolling in from the other team. I walked up to the enemy base and killed their base while ignoring Anivia and Kat. My K/D wasn’t anything special, maybe something like 32-9, but it was one of the first 4v5s I had won on that smurf account.
