Game 2 sarcastic to Ezreal and calling ez out. Ez for whatever reason was afk at that point.
Game 3 harassing Darius. By itself not punishable but cummulatively it is punishable
Game 4 harassing garen. Remember by the code/expectation retaliation is no justification for harassment
Game 5 harassing khazix. Harassing team then again Khazix. and over again.
Not the most toxic player I've seen, but definitely punishable. Read the code and understand what harassment is including sarcasm.
Game 1 starts by giving order with threat to report if not compliend (this is not cool, the guy is not the boss of the world), Gives orders to Mundo and Zilena, then calls Mundo an idiot. These by themselves consititute a punish. I will not go further in Game 1.
Game 2 don't know why i need to explain this, the guy is generally toxic, team noob, back noob, f'ing noob, if you can't see this then you either don't know what your doing or don't care.
This Case is a blatant obvioius punish.
