We need an option to disable mastery emotes.

How annoying is it to get stomped in a gank and have the enemy laner flash their mastery at you. It's basically saying "here you go, I'm better than you and I will win), which is not okay. Riot revolves everything around keeping the match enjoyable for every player, so why not make mastery emotes optional? And then there are people who just go ahead and flash their mastery any chance they have, effectively annoying the enemy team and their team, which is so stupid. They should really make a mute button for mastery emotes.
