Why not being able to mute emotes is absurd
Riot has always had a great approach to how they let players censor behavior which might tilt them. Do you not enjoy your opponent talking shit to you in all chat? No problem here is a mute button. If someone is spam laughing or taunting right infront of you, do you feel the unhealthy urge too all in them even though your pretty sure its not a good idea? No problem here is a mute button. Do you find mastery spam annoying? -> mute button.
Do you find it tilting when your opponent sarcastically spams a thumbs up whenever you make a mistake? Well too fucking bad that is here to stay
It is completely opposite to how Riot has treated every other form of communication. Is this supposed to be special just because they want you to spend RP on it? Wahooo...
