"I desever _____, but I'm stuck in _____ with all the ragers, flamers, and AFKers"
Edit: I spelled deserve wrong. Sorry to those of you who are bothered by this.
If you say this, honestly I can only shake my head and look away knowing that you don't understand humility or how the ladder works.
AFKers, ragers, and flamers will always exist, thats how its probably always going to be, but it's impossible to be stuck because of them, if you get them "every game" and "lanes always feed" then you are not focusing on whats important. A single game is only a single step, and with every step you are given the opportunity to explore where you could have improved.
You simply can't control how other people play.
But you can change how you play. If you improve, you will inevitably climb, even if you do have games where all your teammates fail, which they will, again its inevitable, you just have to shake your head and get over it, because you have the same odds to have a team that completely crushes the enemy. So improve what you can control, don't go screaming at cars on a highway expecting them to turn into koalas.
