Streaks
You need to fix them. I can't have won 25% of yesterday's and today's ranked games (4 wins, 12 losses) because I'm a bad player. I almost dropped TWO divisions today and lost 91 LP. What the hell?! And we all know I'm going to come home from work one of these days and go on an easy mode win streak and be right where I was. Why can't you fix the matchmaking so that the games are not so snowbally and one-sided? maybe 3 games today were close and exciting (win or lose), while the 9 others or whatever were horrible losses or gifted wins. It's tilting, especially since I got a single leaver-buster today because load screen wasn't actually loading. I am so upset with your matchmaking. I prefer to win some and lose some, not go on massive lose streaks and then confusing win-streaks that are more relief than they are exciting.
It doesn't help that junglers get verbally harassed, and that's my main role.
