Tired of people banning my champ (rant)

I'm sure there are a lot of this but I just had the worst match in the many years of playing this game. I don't play ranked much and I'm just a casual player, not terribly good mechanically but I feel like I have a good grasp of what to look for and shot calling. Lately I decided I wanted to take this game more serious and get better at playing the game mechanically and go into ranked. I decided I wanted to play champs like Yasuo and the new Akali to do so and I play top mostly. But people keep banning Yasuo despite hovering the champ and when I ask them why. They either ignore me, flame me or make an excuse saying they weren't paying attention. Despite it showing you a symbol that someone is hovering it during the banning phase. Then when I get into these games on a different champ and maybe don't do well it just makes everything even worse and its like everyone always has to get a swing at me too. They just start ripping into me and I'm just left sitting there baffled by the fact that they're doing this because I wasn't flaming them and I'm not trying to feed either. So now I'm forced to play this game out to 15 mins to try and just forfeit and move onto the next game when they decide to stick it out and just keep playing and never surrender despite how incredibly hard we are losing. So now I'm forced to play this game out for another 5 mins while I get to listen to these people flame the hell out of me. If I mute them then they ping, if I mute ping then I'm left in silence and to get reported after the game for whatever reason they think I deserve it for. Either way I'm basically forced to sit in a losing game for who knows how long because no one knows how to properly finish the game out. I'm so sick of it, I love this game but it really pulls me away from it when every time I'm on I either don't get to play what I want, get flamed, int'ed on, etc. and if I decide that its to much I leave but if I do that then I am guaranteed to get reported because I afk'ed. So why is it not a thing in this game to be able to at least dodge casual matches and not get hit with a queue timer. When I have good people this game is so incredibly fun but as soon as there is just one guy on my team going off it just sets off a domino affect that just ruins the whole match and I am basically guaranteed to get punished in some way for it. I either get a queue timer, afk buster, reported or sit through a entire match of dealing with whatever the hell. I have never int'ed in a game in my whole life and I have gotten into fights with people but I never go so far as to wish things on them or call them something crazy but I have fought with people trying to defend my self and I know I should just mute but after a while it just gets to me. The worst thing I've don is when someone banned my champ I played something stupid like Rakan top which I still try to win and have, that is so rare for me to do though I usually just dodge or play something else. I just want to be able to back out without getting punished basically and that would make this game infinitely better in my opinion. I'm just waiting for the day I somehow get in trouble because to many matches in a row people decided to report me for their childish whining. I am being serious and I'm positive I'm not the only one where I will go multiple games in a row with someone on my team banning my champ or basically ruining the game. Some days they're all great but more often than not its the former. I'm sorry for this really long rant, I just want to find some cool people that want to play together that are trying to learn new champs and doesn't mind losing some to learn. Thank you for reading this if you did. I'm sure I'm missing something though, it can't be that simple or else there would be something already I assume. I just don't know what to do about this, I wan't to play but I am basically forced to come back later after just one dodge because that's just how it is and that's the fault of someone else. its like being kidnapped.

TL;DR: Tired of people ruining league and it feeling like I'm the one who will get punished for someone else making noise. Just want to learn new champs and play with cool people who can handle losing some matches to learn the game and get better and not ban my champ, int, etc.

Edit: well I'm not sure how people got hung up on me saying Yasuo, I said him because he is mechanically challanging and that's what I want to improve(my mechanics). People ban my champs such as Swain and Aatrox as well so it's not a Yasuo exclusive situation. Making a comment that I am the one at fault for wanting to play Yasuo kinda proves my point of the toxic things people do. This whole rant isn't about Yasuo himself but about how toxic people can get in league and how frustrating it can be.
