"BRB, I wanna cut myself"

I had this player coming in from a different game, ranting about some irritating Singed and wanting to cut themselves. I ignored this at first and went into the next game with this person on my team, going on to win it despite his weird tilting quotes here and there.

Where I drew the line is the next queue setup, where after a short time of waiting, he cancelled the queue entry and once again declared he wanted to "cut". At that point I felt like bailing, because if a key ally isn't 100% there are high odds no one else will be either, like a spreading virus of tilt.

I ask of future queues: If you have a previous tilting game, space them out with Normals or PvB matches to cool off. DON'T INSTANTLY JOIN ANOTHER RANKED QUEUE after a tilting game, as you won't be 100% in a scenario where you ABSOLUTELY MUST BE 100%

Secondly, if you're at the point where you want to cut yourself, you shouldn't be on a competitive game whatsoever.
