"Always my team is noob"
This is absolutely wrong. The truth is if you know enough about the game through mechanics, map awareness, and champion/objective control even if you get an afk on your team, you can still win.
I have played on multiple silver/bronze accounts. I've seen much worse than jhin top and a teammate banning your champion (like ad malphite mid with bloodthirster rush 1/14/2 worse)
It takes me a maximum of 1 week to climb out of silver averaging 5 games per day (normally i skip silver 2)
Teammates can make climbing more difficult, but if you truly don't belong in a single elo bracket, then you will eventually climb out. If after two years time, you're still "hardstuck" silver, then it must be one of these cases-
1.) You don't learn from your mistakes
Did you just get cheesed level 1 by the jayce with ignite because you started long sword?
Well don't start long sword next time, and adjust your playstyle so that next time you play the same matchup, you can actually win.
Did you just use your flash but still die to the enemy lee sin?, well don't tp back to that minion overextended into the lane, instead, tp to the turret and wait for the minion wave to push to you instead of risking lee sin coming a second time and killing you again.
Are you getting oppressed by that pantheon in top lane? go back, sell that dorans ring and amplifying tome, buy armor and doran's shield, please don't go back and buy another tome.
2.) You don't ward enough
tooooooooooo many of these cases, I don't know how many times I've been blamed as a jungler when the midlane/top has not placed a single ward the entire game, one big part of warding is learning WHEN to place a ward. (especially in the early game around the 3 minute mark when most junglers finish their second buff and are thirsty for a gank) tracking the enemy jungler is a critical part of not dying, I'd say if you are dying a lot to jungle ganks, this should be seen as your most significant area of improvement.
3.) Little to no map awareness
I'd say this is a major problem in bronze/silver elo. It consists of failing to recognize what is happening around the map.
Are you the toplaner and you see that midlane is getting ganked and running towards you? Instead of walking down so you can assist them, lets keep farming! An Ally has been slain (and now the midlaner is flaming you for cosplaying lee sin and you feel angry cause someone is flaming you so let's start a 10 minute argument in which in the process, we lose a dragon, a turret and 5 kills)
Then when midlane gets ganked again, let's flame them more and oh, whaddya look at that, baron is gone too!
4.) Obsessively playing high skill cap champions
Alright, this one is pretty controversial. I'd say this is less of a problem than the other three, but I 100% recommend you to just straight up dodge if you see one of these on your team-
.
If you see these champions on the enemy team-
It is very likely they will be fed. For the love of god, if you are silver 5, please don't try to main yasuo I don't care what kind of stupid arkadata montage you saw last night, until you reach gold 3+ don't even look at those champions in a ranked game.
To sum it all up, if you ward on a consistent basis, never make the same mistakes more than twice, look at the map very frequently and play meta champions with low-medium skill cap, it is GUARANTEED that you will climb. Even if you get bad teammates. However, most players stuck in bronze/silver think they are the sht and never learn from their mistakes so i doubt this will help you at all if you have that kind of mindset.
