I would like to kindly remind people that even though vayne has a 20% playrate
Her avg. games played are 123.74. that means that she is having old mains come back and play her, people who have had a lot of practice with this champion. Does that mean she still needs nerfs? maybe. probably yes. This does mean that if you saw a vayne carrying in the last game, they were most likely a very experienced vayne player. AKA better than you.
oh i'm sorry downvoters from the fog of war... did i offend you with my statistics?
