Boy am I glad Sion and Kled aren't more popular than they are...
Because I there's much less I can do against their ults than other players. Same goes for anybody else who plays with the game on mute, or people who are deaf.
I might not be deaf, but I am hypersensitive to sound and light, and I get migraines pretty quickly if I don't mute everything in my life. And so I have no way to know that a Sion or a Kled is ulting, and my only counterplay to it is sheer reaction speed.
