Well the thing is, Neon is actually a traditional entry fragging duelist who is relatively easier to play than Yoru. Unlike Yoru, Neon makes room for trades and doesn't reposition at an instant like Yoru, which makes getting value out of her easier. Yoru relies on mind games which, after a certain point, stop working. Hence why Yoru doesn't have long term success in pro games, and teams only play Yoru like, once every 25 games just to try out some new strats to throw the enemy off. But if you look at it, teams have started to learn more about how Yoru works and how teams such as PRX use Yoru and form strats around him. Hence he can easily be countered unlike some other duelists.
