Random little things

Before starting the discussion (that is more a report, than a question-answer topic) I must say my english won't be perfect, but I'll try to explain the problem. I have doubts on the way you let 10.000.000 people troll in ranked matches. I have doubts on the integrity of the tribunal, but that's not the important thing of my speech: I have lots and lots of doubts on how you, Riot, manage to place players who only do 2/8/3 in a silver team and pretend me to go on with ranked. Tell me how a silver 4 can get to 3, 2, 1 and so on if your sistem let us play only with afk people or bronze V. I know I'm ignorant about games mechanics, but I see there lots of discussions about this problem. On 23 ranked matches I never had a team where there wasn't a player who feed or troll or goes afk. I can sincerely tell you this, with no esitation: I'm loosing interest in your game, since players your sistem gets me are so boring. Last thing, I ask you one thing: don't block this thread. If you want to punish me, just ban my account. I want to read some answers by flamers like me (becouse this game forces you to be a flamer, nothing personal). But first of all I want some Riot's answers, becouse I can't explain why normal games I get nice team and ranked I get cancer team. In every case, goodbye Riot!
