Just delete Vayne from the game already
That champ is complete garbage. She is either trash tier or an abomination.
Last game she was on the enemy team going 0/5, she was feeding so hard her support just left her lane and let her farm on her own. The moment she finished Bortk she could just 1vs1 anybody in my team regardless if they were fed or not. Fighting Vayne is usually a lose/lose situation as long as she has the ult she is basically completely invisible during the fight, its like fighting against the very old invisible Evelynn with sunfire cape stacking, you basically cant do anything about it. At least you could use a pink some seasons ago to see invisible enemies but I guess it was a great move to remove that feature from the game.
Thing is, if they nerf her she will become useless again, if she stays like this is cancer.
