Ok, so I'm 125/128. Honestly I was fearing it will be far worse. Looking at the last two days where I lost two 4v5 games which we should won have if we had 5 players, it makes me a little sad. Oh well. Can't complain.
You should report the trolls at every chance, they do it because they think they wont ever get penalized(which is completely untrue, people are penalized for those behaviors). I find it highly improbable that you have a 10% win rate because the other team is just as likely to have trolls as your team.
Please give us your ingame name so we can track your previous games / allies (via lolking.net for example) and then we can get some more data to help you. Or perhaps use lolreplay and offer a few replays to us so we can see how you do. Frankly, I'd make a new account and start over.
