Vayne is broken in Overcharge mode
You can't duel a Vayne due to her 1v1 power, you can't outrange her with Caitlyn due to too many vents, Draven's mobility is screwed up by too many narrow corridors (making it hard to catch his axes), and Vayne doesn't even need to try in order to pin you to a wall (which is certain death).
I must request that Vayne receive a specific nerf in this mode. I have tried just about everything against her and nothing works. If Riot (not the community) has a reason why she's not broken in this mode, they need to prove me wrong.
