Leaver Buster Because My Team Being Brats.

Ok. So I join a game of blind pick. I said JG like 3 times. Pressed WW then locked in. Then Tahm (The New Champ) apparently called it before me. But I didn't see it because I joined late or something. So he ends up picking JG anyways and locking in. So now we have a Duo-Jg. (Stupid). So the game starts and I go to red. I get it down and i'm fixing to smite it when he swallows me, Smites it, (Steals it), So i'm just sitting here like. "What a f'ing c^nt". So I move on to the next thing. And guess what he does. He does the same dang thing. I was thinking about going to the next one. But I realized he's just gonna keep on with his bs. He didn't even jg by his self. He just followed me. If I went to spawn. He went to spawn. If I just sat in front of the jg monster so did he. So I sat there for like 5 mins hoping he would go away. But he didn't. So I just sat there. About 15 mins ( And guess what, So did he). Then my team begins to say that I am trolling. And to report me AFK. I told them all what this guy is f'ing doing. Buuuut noooo. He "called it first" Even though I didn't see it. So my whole team is sitting here cussing me out. So I just sit in spawn for like the last 5 mins of the game. The enemy is camping us. And this Tahm guy is just f'ing trolling away. He keeps swallowing people and spitting them out of spawn to get us killed. Which actually did get me killed twice. So after game they're all still cussing me out blah blah blah. Then I get the message that I have low priority que for 5 games. Seriously riot. If you even make people mad for no reason. And they report you. Even though you did nothing wrong. You can get low priority que? WTF? I'm just waiting til I get reported by some brat for no reason then I get banned. Bs. P.s. I just checked to see how long I have to wait. And guess what 20 f'ing mins before each game. For 5 f'ing games. That's over a hour of waiting for just 5 games.
