The League System.

Alright so im sure all of us have had an afk in ranked, or a troll, or feeder etc.. and yeah its aggravating because you lose LP and get a loss in your history, but in lower elos its getting ridiculous. Ive been bronze one since january and can tell you first hand that its a problem. If I had won this game recently I would be in silver promos for the first time, I was so excited so I queue'd up. Draven got fed and bot lane did amazing but then a summoner has disconnected top afk'd and we lost, I figured it happens and went back into play however I found myself winning a game then getting a troll right after and losing the LP agin, I feel like every other game I have an afk or feeder and no matter how good I do I cant carry the game 4v5 or 3v5. I think a syste should be put in place to effectively deal with trolls and afkers so that when im in my promos I dont have to deal with the 0/12 katarina jungle x_x
