elo hell

I am stuck in elo hell, I am there because I got screwed in my 10 games, 4 afks, ended up going 4 for 10 (basically 4 and 2 rating in the rest) Because of this I got thrown into B5 and there is no way out. In order to get to B4, its easy, however to get out of B4 is impossible due to the AFKs (1 for 3 games and the fact that people in B5 dont care if they lose and end up feeding. So for you geniuses out there that claim I need to itemize better and play better, here is some math for you... For a B4 win, you get 14 points, for a loss, you get 20, therefore in order to get out of B4, here is the streak you need to go on to get out, either 7 and 0, 9 and 1, 12 and 2, 15 and 3 and so on... Riot's low end ranking system is broken because an AFK will occur 1 in 3 to 4 games and your success rate with AFK no matter how good you claim to be is 1 in 10. The problem is AFKs ruin the ranking system and are very common in B4/B5 games. These streaks to advance are impossible unless you are grouped with experienced players every game. I invite anyone to solo out of B5, then post your comments, otherwise don't waste my time trying to say it is my fault im stuck here...
