Kat in bots, Kat vs. Team

So, I know what your thinking, bot game, scrub lords, who cares... BUT, I feel like venting after suffering through a stressful encounter with a new type of toxic I had never seen before. After just buying (to counter all of you pesky and players) I wanted to relax and try him out in bots. Well, I get into lobby and immediately two people autolock and and don't call lane. "No big deal, its bots, that's normal" We get into game and mid is left open, I'm going fiddle sup and the kat is in to with Irelia getting first blood at 45 seconds, "No big deal, their obv blowing off steam"

Then at 5 minutes in I hear "LEGENDARY!" only to my horror discover that the kat had roamed mid, then top again, then teleported in and stole both kills that should've been my adc's, and that's when I have a problem. But it only gets worse....

**Ending score for katarina (IN A BOT GAME): 50/1/7 **(she only died once so as to steal my kill, after I ulted)

I asked the katarina to stop ks'ing, and I did so in a calm and polite manner, and the only thing she said the whole game, in response to the clear and blatant insult I had just handed her was:** "HaHa." ** **"HaHa." ** That put me on tilt so hard...in a bot game...because of my own teammate's actions....

Rito, I love you, I really do. I shower you with my green paper, my lemonaid stand earnings, my credit card number, my piggy bank full of broken dreams. All I as is that people like this be dealt with swiftly, and be handed a serious slap on the wrist. Because a game full of fun, at the expense of others, especially your own team just isn't right.

TL;DR VERSION: I'm complaining about people who play kat in bot games and steal EVERY FREAKING KILL
