Silver IV is exactly where elo hell's at

"ELO hell is wherever my exact division is"

Youre going to have to roam as early as you can and try to get other lanes ahead. Say if the other laner backs, you have to quickly run down to a promising lane and try to help snowball them. You can also risk roaming when you have the gold/level advantage. say if youre one or two whole levels ahead, then you can try to gank, although its much riskier if the opponent is in lane. Push the minions to their turret, then quickly run down to another lane to help gank.

You cant just win youre lane and expect to win. This is a team game where youll have to try to help youre team at every chance. It will do you no good to be greedy in lane and just try to get rich off your lane. If youre going for good ganks/plays, it should always be worth the time and effort.

Elo hell isn't a thing you aren't trapped you just are BAD no im kidding but u make mistakes and thats why you are where you are bronze to challenger

Unless bot is really far behind, come bot. Literally 90% of the games I've had the team that comes bot first wins. I've had games where mid and jungle come bot only to have top TP in as well to get in on the fight. Even if you don't get kills, it's pretty hard for 2 people to stop 5 from taking your tower.

Now, if they've fed 10 kills in 10 minutes in 2v2's, then yeah, only help them if the enemy bot lane is trying to take a tier two.

I have to admit that youre not entirely wrong. if elohell exists its around your league because fresh lvl 30 accounts will start somewhere around that elo. still: if you are good enough for gold or anything you would be climbing faster. your kda, farm and damage is good, you main few champs, thats good aswell. i do believe you are a mechanically good player and able to win most lanes, but youre not losing without any reason. so most likely your decision making or general strategically thinking is not good (or you flame too much and get tilted easily -> both leads to poor decision making).

so the best thing for you seems to be to change your playstyle. you can do 2 things pretty much: roam and help others (i dont recommend this in low elo) or stomp your lane so hard and get fed enough so you force the enemy to put a lot of ressources into stoping you while you are just splitpushing the whole game. if you split and they send weak people: kill them and continue, if they send enough people that you cant kill them: just leave, they still had to invest the time of several members for you. i really recommend you to test if the splitpush playstyle fits you, since its the best way to carry low elo soloq. renekton is a real good champ here, so are trundle, fiora, nasus, jax, irelia etc.. yasuo can work, but i dont like him that much since he is squishy, lacks sustain and needs to scale. i really love trundle for this because hes fairly tanky and can take structures pretty fast. plus he is basically unkillable in a 1v1 and can force fights pretty good aswell as end them with his pillar.

splitpushing is also a great way to make decision making less meaningful since its a forgiving playstyle. when youre strong enough you can even kill someone when you overstay.
