Why! Just Why!

I Honestly can say, I hate the LoL Ranking system. Why! Well because it is very frustrating to depend on 4 other Random people who u don't know from a whole in the wall to move up. I've lost about 5 or 6 Series because of teams in bronze who feed, troll, or think they know everything it is to know about LoL. I do not think the system is fair for players who take the game seriously and want to do good. So for me to play to move up with 4 other randoms who don't really care about winning the game is unfair to me. I rather be paired up with 4 other people who are in a series, so we all know what is at stake. Not having a Dude pick Ryze because of STK having success from that champ. Then dude goes 0 and 3 with Zero help to the team. etc.... Some people in rank just use it to practice champs. totally not fair or cool at all. Never getting out of Bronze!
