Why LoL sucks and what is my experience about the game.

I started playing 12.31.2015. now it's 4.14.2018. Before game was more fun, there wasn't bitch-ass champs that could flash million times on lane in a few sec.Game was never balanced for real from what I saw,but Riot don't adapt game to everyone i mean they are focused on pro play so I guess I will quit the game. Removing poacher's knife made lee sin players really mad I guess,I was never some serious lee player but still they did it because it gives too much vision if im informed correctly.1 man can't win the game but 1 man can lose it.Balance is awful as i said I mean let's put it like this:"I will play Pantheon and if I fall off i can suck myself also there is that guy playing Vayne or Yasuo who can be 0.50.0 and still in late game when get some items be 100.52.10 (Ok thats unrealistic stats but you get the point)".Riot thinks probably "Those champs has weak early so it's alright to come back in late" well its not it sucks rly Im currently in Gold IV and still some champs are insane in late doesn't matter how hard they wall off ... and still there is that "If you know how to play you will end the game" well u cant end game solo without your team mates unless your smurfing but thats not my point.So its or balance the game for everyone not only for pro players.It sucks already I played few games recently and game is not fun anymore so don't be surprised by more people quiting the game.So many times I lost (and won) because of how bad my team mates were even if I win my lane if all others lose its done, how many times I remember playing jg and every single lane was losing, I didnt know where to start with ganking like even if I gank its still not very effective because others will be or killed by enemy laner, jungler, I couldnt babysit only 1 lane yet still I couldnt leave.
