Fix damage or do something to burst, its getting out of control

I just played a game against a Diana, I know she isn't considered OP but what the fuck. She did nothing in lane, and the second she hits 6 she one shots everyone she looks at. Not to mention if she doesn't for what ever reason she has her 3 aas which fuck anyone up, including the wet napkin turrets. I was a healthy Swain and it didn't matter AT ALL. If she got in R range, she didn't even need the reset she would blow me up, it's fucking awful. I watched her run up out of fog and just R our twitch and he was gone thats it, no fucking thought or skill, just one fucking button, I don't care if you argue it's not broken it feels like shit to play against.

And in the same game, there was a Shaco. I mean what at Riot is letting this shit go unscathed, why can he walk up to someone while being COMPLETELY invisible and she aaing and hitting his Shiv, which he can't miss and you die. Again I don't care if you think it's broken or not. IT"S NOT FUCKING FUN TO PLAY AGAINST. Hell, as a Swain with around 3k health I could nearly one shot people, WHY? Why does a sustain mage need to do that kind of damage. I don't fucking care about high elo, all I want as a casual player is to be able to CASUALLY play the game without having to need super fucking hero reactions just to fucking live, because the other team has a champion with a point and click assassination that require ZERO thought.

I would love to play ranked, but this kind of shit doesn't disappear in ranked, and I'm not comfortable losing over and over again, because one person on there team can fucking one shot who ever they please cause the champ they have has such reliable burst that it makes the only form of counter play either stacking resist, which feels like shit on a damage champ, or fucking sit in base, cause that's the only tower that's useful for anything.

Fucking down vote me, I don't care, this is a rant. I just want to play the league I fell in love with, the league where every role felt like it matter, the league where I wasn't dying as fast as I was in CoD. I want the league where I have to think to win a duel or a teamfight not get lucky with one move (Zoe E) and win automatically. This piece of shit feels awful. I get urges all the time to play, and when I do I get so disappointed that I spent money on this game.

If any of you agree with me, great, I'm glad, and for those of you who don't fine, this isn't a post backed by fact, or sensible unbiased situations. I just can't stand to see this game take this horrendous turn, and how little Riot is concerned with the damage creep that plagues this once brilliant game.

I want assassins to be assassins. I don't want ever single champion in the game to steal the title.

Ok I'm done, and if you read all of this, why?
