I don't know how to climb anymore

Whenever I heard people saying ranked was luck in previous seasons, I just laughed because I figured in 75% of your games, you can still carry.

But recently, maybe it's tilt though I don't feel upset or anything like usual, I just can't seem to win as a result of my skill. I win some games and think I've contributed nothing and still was a stomp yet other games where I try my hardest, all I get is a slow suffocating defeat that could've been over 20 minutes ago.

It feels no matter what I do, I can't rustle up a win unless the entirety of the enemy team is really bad but if even one member on my team is bad, automatic -18LP

I help the jungler leash, help them when they get invaded, roam and counter-roam, pick MVPs from the enemy team, have superior ward coverage with buying multiple pinks even. I prevent myself from having an excessive amount of deaths and keep towers from going down too early, help out every dragon, every baron possible and yet

none of that seems to matter

We still lose because bloody 3/8 adc gets caught and they storm down mid tanking turret after turret. It feels the ONLY way to win is picking a bruiser/fighter because they are durable enough to be a nuisance (1/10 jax with tri force still tanking better than a damn fighter fed Vi) and can feed to high hell and still carry with one stupid item.

This season sucks and this game is becoming less fun as a result.
