Thinking about quitting league...?

I'm not sure where to even start with this post, i'm not writing it out of anger from a game i just played or something, it's just coming to a realization that 80% of the time i'm playing the game, i'm just not having fun. I'm wondering if this is just me being burned out with the game or is it a more mainstream opinion, that the game has just become boring. I have almost 800 ranked games now, climbed from b5 to gold this season, but somewhere along the last 4-5 patches i slowly just lost interest in the game...? I don't like the tank meta, maybe it's bc im an adc main, but it just feels like the game consists mainly of these big 5v5 fights somewhere in the jg and the team who is able to engage first and chain more cc wins. i will build QSS and bansh, but it feels like in team fights my role is mainly trying not to die, and i'm having a hard time telling if im having fun because im either stuned most of the game, or annie tibers instantly killed. i play mid and jg, also some sup, and it feels less annoying in that sense, but then i still feel the same way, who ever seems to have the better hard engage comp or is able to chain more cc just win every time. maybe it's the lvl i'm at, and it was always like this but i didn't know, but the better i get at the game, the less fun i have at each tier it seems. am i the only one feeling like this? like there's something about the game that changed along the way that i don't really feel like playing it at all anymore. and when i take 800 games and estimate how many 4v5's ive had since the start of this season, it makes me even more mad, i feel like half the time i play i'm wasting time and should go find another game
