Playing LoL since Season 3 but thinking of quitting now because of matchmaking

This ridicolous coin flip games have nothing to do with fun and fair competition anymore.

My last game: https://abload.de/img/lolp4kmu.png

Two Master+ Smurf-Premades in a high Plat game. Guess who won. And this is not even rare. I have smurfs in 50% of my games. The other 50% are weird new accounts with 7 games (all losses), trolls and autofills.

Actually i dont enjoy this fucking game anymore because of this broken matchmaking since season start. The only reason why i play this is because i finaly want to hit D4 and then leave it until its playable again! But the several times where i was in Dia Promos last week were even more disgusting than my avarage games.

I mean... yeah i get it: i am not a Pro and a Master Player would probably climb easy through my elo. But when you are close to your skillcap its hard to win games who arent balanced AT ALL. Especially when you're playing a champion with whom it's difficult to carry and where u depend on your team (like Voli).

The weird thing is... Now in S9 I get most of my game invites between 0 and 30 seconds (Plat1/Jungle/EUW) and the matchmaking is WAY more unbalanced and worse than S8 and Pre-Season, where my game invites were ALWAYS around 1:30-1:40 in the same Elo. I mean, if you shorten the queue by 80% it's no wonder that you have to pay for it with something else. In this case the quality of balanced games. It's totally obvious that you can't have both: short queue and good balance. I don't understand why they did it. I was totally fine with 1:30. Hell I would even be fine with 3 minutes if I have teammates on my Skill-Level then.

Riot pls... if u cant find balanced games in 30 seconds then just STOP it! Or at least do somnething against this shitty smurf problem!
