Bad ADC/Support stories?
My worst support is a Sona who sat there raging because I (Ezreal) didn't want to fight the enemy Nidalee and MF who had already had a kill on her because she decided to fight them 2v1 with around 200 health. She blamed me for the fact that they out damaged us too.
My worst ADC came when I was Bard. I was Top trying to help a Morgana and Lee Sin keep the enemy Nasus Under control , so Caitlyn decides it would be a perfect time to fight. 2v1 and dies. She does this at least 2 more times while nobody is there to help her. Post game she says "why is bard even a thing, it shouldn't be."
