Wannabe Kayn Player

So I'm going to go off on a lil' bit of a rant, here. This just barely happened to me, and, to be honest, it pisses me off. Here we go.

Today, I had nothing to do. I had no responsibilities to take care of, no friends were free to do anything with me, etc. So, I hop into a League game. After about three different champ selects, where someone had left, I found one with someone who wanted to play Kayn, the new champion. We'll call this player Billy. They had first pick. Knowing this and the fact that Kayn is pretty broken right now, the player hovering Zac (we'll call him Caleb), rightfully, banned Kayn away. Once Billy saw this, he said some passive-aggressive things in chat, then proceeded to have his friend ban Zac, and himself ban the champion I was going to play, Wukong. Now, I didn't do anything to deserve this. I didn't say anything to him in chat, and I banned Darius. I won't sugarcoat it, I was beyond triggered. Triggered would be an understatement. I started raging in chat, saying that it was a dick move and that I didn't do anything to him to deserve this. The next thing he said was, "Whoops Shrugs"

ARE YOU SERIOUS?!? THAT'S ALL YOU HAVE TO SAY?? WUKONG ISN'T EVEN A POPULAR PICK RIGHT NOW, SO HE KNEW WHAT HE WAS DOING!!

Calming down now. But seriously, people like him make me mad. I dodged that champ select, because I didn't want to play with him or his friend. Sad day.
