We have chat mute, ping mute, and emote mute...
So why can't we also get mastery muted?
These shit are as annoying as seeing some asshole flaming like crazy, or hearing and seeing the danger ping and question mark, and the emotes that ranges from god knows what riot even made to god knows what riot will ever make. Oh wow you're level 7 good to know. No need to spam it and have it cover your entire screen and my screen, blinding you and away.
So again: why can't we get mastery muted?
"But But dalekzec! How will they brag on how good they are with their champion?" You know, if daleks were real (even 1), no mastery 7 will save your ass with a toilet pump to your face and a laser shooting you to a lifeless corpse. In other words: Who gives a fuck?
