Why?
So, I just had a game where I was playing as Janna right. And we were losing very hard for about the first 20 minutes because our top-laner didn't do so well. I was 1/1/11 at the end of the game. Anyways, I digress, my mid laner is a 5 and 1 Azir with at least 70 more cs than everyone else in the game. We started to make a strong comeback and their Poppy dives on my ADC and I kill her with my whirlwind, which nets me a blue buff. I go back to base, our Azir, who ALREADY HAS A BLUE BUFF, calls me a "toxic piece of shit" and proceeds to sell all his items and run down mid and feed until we lost because I "took" "his" buff. What causes people to do this? Is it some sort of extreme heated temper or mental imbalance? I don't understand.
