Why is every game played trash?

Simple as the title says.

I'm on a 50 game winning streak, 35 games all lanes win and enemy jungler gets shit on and it's ff @ 15 5 of the games 2/3 lanes win with top lane feeding or mid lane feeding, the fed carry can't do anything against the might of an entire fed team pushing their nexus. The other 10 games we win with the a laner and either another solo laner or jungler fed on the enemy team or all lanes but bot feed on the enemy team and then it's a bit of a struggle but still an easy win.

I'm on a 37 game losing streak, same exact shit, same trash gameplay, but vise versa, I'm tilted but playing excessively well, 4-2-2, every other teamate is 0-6 or more and inting and I am powerless to change the outcome of the game.

To exagerate my point more, a few of my friends have emphasized to me the imbalance in skill in matchmaking through themselves actually running it down every lane and inting through the game to make sure they lose during their winstreaks and they still win, lopsided win, with instead of 35-2 it's 35-12 or so. Every game is always lopsided.

I also think it's an anti comeback mechanic that my teamates that farm up and are 1-19 with 150 cs have 1000 gold bounties if they haven't died in so much farm time. This bounty system suck.

Too much gold in the game, full build comes far too quickly -Bounty system sucks -First blood turret gold was never removed and was hated until people forgot about it -First blood turret gets piled on with 5 plates -Cannon minions give 60+ gold -Tower local gold gives 250 gold

Honestly just too much gold

TL: DR Matchmaking is trash and is worse now than ever before, and should be reverted to the way it was a few seasons ago.
