What the hell is wrong with this game's client?

I have a Ryzen 5 1600, GTX 1070, Wired Internet with 70MB/s WIRED Internet. Running the game 1600x900 Full Spec. This is ridiculous, I was kicked out of my ranked game. RIOT SCREW YOU. On top of a shitty season, I was literally 1 game away from promos now I have to deal with this shit and play another just to get to my promos I've lost 3 times and been demoted back down from when I did win twice. This game is horrible and I'm fuckign sick of it.

EDIT: Next game, restarted client, couldn't change runes and on top of that had a troll feeder Anivia support and got camped mid, I straight up left, this isn't enjoyable. I'm done, quitting this game, Goodbye Riot fuck you and your shit game I'm sick of fucking losing all the time this game has ruined my life.
