Why I can't get carried even once

I understand that you have to play better than your enemies to carry a game and you should always blame yourself for losing but how come I never get carried by my team? Why am I supposed to carry my team in every game to prove that I belong in a higher elo but my team never has the obligation to carry me?

Seriously, the number of times I got carried af are less than 100 and I play since season 2. I really want to feed my ass off like the rest of my teammates and get a free win because of 1 or 2 people but that never happens. If I feed I will lose because my team can't carry but if my team feeds like hell I have to magically carry them.

I don't have trouble carrying games because I know what champions to play with when try harding ( Jax, Irelia, Akali, Evelynn, Kayn ) but I want to play champs that cant solo carry once in a while but if I do that then there wont be a person in my team to carry the game unless I snowball or my team plays like normal and the scores are even.

Normal games dont count because you are matched with random elo but in ranked I don't have the privilege to play like shit and still win because nobody will carry me while my team will get a win while being afk or going 0-20.
