What are your tips for being untiltable aside from /mute all?
Personally, I disable enemy emotes, and I mute the in game announcer. There is nothing more tilting than the constant audio of "AN ALLY AS BEEN SLAIN" to make me boil over in rage at "HOW DARE MY TEAM FEED! WTF?! FUCK RIOT! FUCK EVERYTHING! GG GAMES OVER!" (no blame on myself for the altered and worse state of mind). I've steadily been able to focus on the game by removing the negative input of other people's mistakes, which I can't control, and become better able to only focus on myself and see my own mistakes. It makes the whole learning process, even in a steam rolled game, much more palatable.
