I had an idea to prevent tilt sometimes and lose nerves and temper. ( this idea is addressed to riot employees )
After a few games you could write a short message and send it to everyone in a specific region, like when you do with notifications.
That message may contain a short text with a motivational quote, a meme, advice or an idea to do after the game!
Everyone that had a bad day or bad games could use some help, a good laugh or some relief of stress! (and im not talking about taking a deep breath or drinking some water, thats like the trigger to show you that you are tilted and go chill yourself out)
Like imagine losing a trolled game, and then riot pops you meme with : Don't worry flamers, you know i have the high ground ( with Obi-wan in the background)
Or just say: You see the the snow outside? Me neither, im as disappointed in life as you are :|
Maybe: Go check on your gf, i think shes burning the kitchen ( if you dont have a gf, still go check the kitchen, you never know when sh*t is about to go down)
I know most of us take the phone as fast as we end a game or check on other notifications on our PC, but this is like we are already annoyed to play the game so we find ourselves a different means of entertainment!
We all deserve some sugar, if your loved ones dont give you any, then Riot should :)
