Ok so I didn't bother to read any of this bullshit above, because I can tell just by looking at a few sentences it is ignorant, close minded, and offensive thoughts that have no actual reason to help the situation at hand.
Screw all your statistics, I actually did real statistics myself, and recorded every one of my games for the past 2 weeks on a spreadsheet with my finishing record, and with the win or loss, and possible reasons for loss, and every other team member's record.
I played 20 games in the past 2 weeks. My average K/D/A ratio was 2.6/3.8/18.4. I won 7/20 games. 13 losses, and 4 of those games were losses because it ended up being a 4v5, because one person either disconnected, left the game, rage quitted, or went afk. 3 of those games was lost just because the other team was flat out better then our team. The rest of the 6 losses can be broken down into this:
-2 games where the jungler didn't even know how to jungle, 1 of them was his first time, and the other 1 only ganked middle lane, why I don't even know.
-2 of those games were lost because at least one person on our team went 0 kills, and over 10 deaths, with a few assists.
-1 of those games was because of a troll that just ran into the enemy base constantly.
-1 game was lost because 3 people fought over a lane, and ended up going in the top lane all of them and then dying... and this continued all game.
I played support for all those 20 games, and I had a really good ADC.
3/20 of those games, I lost because the other team was just better, so yes, it could be because of me, because I need to play better. But the other games should have been wins, I shouldn't have had 13 losses, with nearly 80% of them being because of other people.
And those are REAL facts for you, because if you want the spreadsheet in Excel I can give it to you.
And oh, the average K/D/A of my teammates: 7/12/5
I performed way better than my teammates.
