First of all ADC's carry the game....Supports carry the ADC's. Bad support? Lanes over maybe even game. Good support? Make you look like a god and says nothing when they make epic plays for the carry to get kills then everyone says "Good Job {insertnamehere}" :)
Secondly Everyone needs to stop blasting the OP. Gotta vent when you gotta vent. Is it possible Vayne was scripting? Yes. Do we know if she wasn't? No. Will anything be done to the Vayne from a single game report? Probably not. Even if they do permaban her you'd never know. You'll probably never see that Vayne again. But what do I know I'm only silver.
