Change Nocturne's "Dynamic Gameplay Button"
As fun as semi-global, unstoppable, unblockable, undodgeable, unflashable, point and click, near instant one-shots are, having literally any counterplay besides "Flash over a wall after his ult lands but before the fear hits and pray his flash isn't also up too".
INB4 the usual bombardment of boards posts, No, I'm not saying he is broken. I do not care what his win rate is.
The -point- is that Nocturne's ult does not have any form of meaningful counterplay to the vast majority of champions, especially if he gets even slightly ahead.
