Ya I have a friend who started playing league years before I did. He was already lvl 30 and played hundreds of ranked games (plus maybe a thousand+ unranked) when I started. I used to listen to him and ask him questions. Then I eventually learned more than him, and I'm kind of a try hard who has to be the best I can be at whatever I try, so I try to be as efficient as possible and pick up on patterns n such for predicting movements and what not.
This friend is not like that. It's like he doesn't think any deeper than what worked for him before, must work again. Doesn't think about maybe it worked cuz your lane opponent was unskilled or whatever. Theres a lot of circumstantial shit in this game.
I'm now silver 3, and my friend is still bronze 5. He's always been bronze 5. There are a lot of people who actually are what you're complaining about. They will never learn.
However, I started playing this game during the preseason last season. My first season of ranked, I climbed out of bronze after a couple hundred games in ranked. This season I climbed out after maybe 60 or so games. Now, I know you said you're not saying you're good or a God... but maybe you should focus on yourself a little more. If you can't get yourself out of bronze, idk what your problem is. For me, it's a sure thing. It's easy to get out of bronze. To others, it's easy to get out of silver. Not for me, so maybe I am a true silver player. In that same vein, maybe you're a true bronze player.
