Some champions make Lower Elo impossible to rank up in

As I've been stuck in silver forever, that a few champs are actually completely impossible to face in lower elo even when my team does excellent. Players in low elo just don't understand whether CC or healing or building a certain way is suppose to help their gameplay...

and no it's not always the champions fault, I see players consistently stick to "recommended" items to build which irks me because half the time that player is building the wrong item into an enemy. Strong AP mid laner and your an ad assassin? Build to start.... Health regen stopping you from killing the enemy? consider Is your enemy building just attack speed? how about

But sometimes there are champs that are to easy for lower elo players to play, but to hard for elo players to face... Trynd has 1 job, very linear, build attack speed and split push. The issue is, he can continue to split additional time while his ult is up and successfully escape afterwards. Something needs tuned on this champ... either turrets need to do dmg even when he's in his ult, or his dash needs reworked into a different spell. Some would say "well his dash is to help him catch up to an enemy"... no his slow is, his dash is unneccessary. is an example of such. He doesn't require a dash to catch an enemy when he has a point and click slow to chase with. Chogath... So he builds tank but does like 1000+ dmg, TRUE DAMAGE might I add, and increases in size. He begins a literal wall by late game than just slowly closes in on you and will secure a win unless your teams entire resources focus him. So don't focus him? Well when his ult does that much damage, as a point-and-click, it's nearly impossible to do so. She gets fed, good luck. I don't even know what to say about this champ other than I believe she is good in high elo and low elo. It's been like 6 patches and this champs still not got a nerf to him. Maybe remove his ult reset? Maybe adjust his stuns hitbox to be accurate? Maybe change how he gains life back after taking damage? Just do something. His mechanics are so simple that he's just to easy of a pick and is perma-ban atm. Stand in the back and auto from the furthest range possible whilst doing a hellofatonof damage a second. She is doing way to good atm and her Win R/Pick R are super high that it bothers me how she hasn't been nerfed. There's very very few ways to play against her, requiring that you MUST have a tank and that you MUST have some sort of CC to both stop her and the tanks peeling for her. Most of the time, you don't get that in low elo. So is he tank? Is he an AP carry? Is he a Glass cannon? Is he a bruiser? I'm so confused as to what the intended purpose of this champ is and I think Riot is too which is why they haven't done anything about him. Like make him either a tank or AP carry, but don't make him both. Right now his sustain is entirely to much that he combos in and then walks out without a scratch cause' of his passive. It completely baffles me how almost no one in low elo knows how to play against this champ. He doesn't do much, just like any other assassin, and it's not like he forces your screen to go absurdly dark like to avoid him. But for some reason he just seems to stomp in any game I face him in cause' I guess there isn't a "low elo" way to counter him yet? I'm sure you could take or to counter him but even then, it's almost as if my jungles play completely into him... These champs almost 99% of the time when I have a jungle facing him... I literally have to ban this champ every game cause' no matter if I play or , I still can't seem to keep him from destroying my games. His power is just to much to handle, and as most people in low elo have no concept of farming under turret or dodging skill shots, he makes playing against him even harder when you aren't playing those two supports.
