Just started ranking after two years of playing normals
Carried and won my first 8 games. In my 9th, one of my teammates had a bad game and fed an Irelia 8 kills in laning phase. This cost us the game.
My question is, how do people deal with this sort of thing? It's never bothered me in the normal games I've played until this point but now that I'm trying to rank up it actually matters. It's so upsetting to see my LP DROP from 100 to 84. I ended up reporting the guy for intentional feeding even though I'm sure he was trying his best, and reporting the fed Irelia for carrying so hard and ruining my game. I know that's not fair in the slightest, but I needed to do something to channel my distress.
How to most people cope with losing a ranked game due to teammates?
