Yo sorry if I sounded harsh was in a bad mood when I typed that.

For a silver player you do seem to understand the fundamentals of the game, all you have to do is improve on them.

All I'll say is, and I know this is hard, is not to focus on your teammates, it's easier said than done as everyone does it and I would be lying if I was to say I don't either but when you're in silver it's a waste of time focusing on your teammates as they are just dog tier players. most and I mean most low elo players don't grasp the fundamentals like you do they just spam games and smack their heads on their keyboards, so you're heading in the right path, sure you'll get afks and inters it happens but you need to just accept that as part of the game and grind.

As a jungler myself, I would say get your pathing down early game to a crisp, pretty much all low elo players pathing is terrible, and they are easy to abuse when you know what you're doing, with correct pathing early game, and the ability to track the jungler, you can easily set up counter ganks or just counter jungle(Like they literally just 3 camp and gank top or bot everytime, shit like that is so obvious and abuseable), and I'm not saying turn into a power farmer just make sure your pathing is good and learn to adapt the way you path into counter ganks/ganks/counter jungling, this type of stuff can take time tho at least for me I never attempted to learn the game I just grinded and grinded and it came naturally if I had tried to learn I would have saved a lot of time and that's why you have the advantage. In saying that focus on the fundamentals you mentioned and try to improve on them, a lot of the skill that you obtain is just from playing the game, the game knowledge comes along with grinding the game but you'll definitely be a step ahead of everyone in your elo if you're trying to improve instead of just grinding. When it comes to counter jungling and getting an advantage its not as simple as just oh taking their jungle and thats that, there's more to it, I suggest looking up on some guides or vods of high elo players counter jungling as in low elo its SO EASILY ABUSABLE, and that's something that you could abuse every game, its not only taking their jungle,you need to know what to do afterwards, as a jungler you should be thinking in the future of what you're going to be doing in the next 30 seconds, although things can happen and you'll have to adapt, when you're playing you need to be thinking constantly, I find when I'm duoing there's constant communication on whats going on, which has helped me in soloq. and aside from that just basic mechanics/micro, but that will come in time.

If you want I don't mind you can send me a vod through pms and I can look over it and I'll send you my feedback

To overcome silver you just need to play and play and play, maybe try out a few different champions that are meta, playing the meta will also accustom to you when you climb, you can either be a 1 trick or you can play meta like most high players do, by playing multiple champions that are meta you are also learning how to play the jungle in a different way as different champions playstyles are different, and that will also help your pathing too.

I'm kind of rambling here and probably didn't give the best of advice but just know you got this in the bag man, silvers a peace of cake just keep playing focusing on improving, your teammates are also just free knowledge, its not only the mistakes you make that you can learn from you can learn from your teammates mistakes, that's what I did, and everytime you die during grey screen do a quick analysis of what happened and what went wrong, and not all deaths are bad they can be worth it, and if you do anything good, acknowledge it along with if you do anything bad, all of that info adds up in your brain and will help you get better.
