You don't deserve to climb

If all you do is go even in lane and expect to win. You are mid, broke even with mid laner but made no plays on side lanes or the enemy laner successfully roamed just as much as you did? Why do you think you deserve to climb over the enemy mid laner? Just because you didn't feed?

Even if you are on a hyper carry, surviving lane doesn't mean you deserve to win the game. You took the risk of playing a champ that does nothing but mid/late game and you lost the gamble because you couldn't carry your team early.

Did you stay calm? Not yell at your team to tilt them? Did you focus on objectives instead of chasing dumb kills? Did you back at proper times and not back for some stupid item when you could be taking a tower or another objective? Did you make plays? Did you use proper decision making and not stupid 1 for 1 trades?

Look at yourself before you think you didn't deserve to lose a game or that you deserve to be higher ELO. There is always something you could of done. Sure some games are literally unwinnable but there are always games you could of won if you didn't miss crucial skillshots or made the right calls or made any call at all rather than sitting around.

Improve yourself!
