How is Vayne OP?
I hate the champ. I ban her in my ranked because I'm tired of seeing her along with the other juggernauts, but is she as OP as everyone is saying she is? No, because the only thing that's making her so strong is her team fights, and her strength in solo queue, and pub-stomping bad positioning. I assure you if you pick an adc that can do more than just kill champions you'll have a huge advantage.
