Flex game ranks | Pretty f*cking butthurt

This is the ranking of my last game. (Note: these are solo queue ranks)

Enemy Team

1. Ivern (Arrowkill) Diamond 4
2. Janna (All You) Silver 4
3. Tristana (longrenwang) Platinum 5
4. Fiora (JW Stargazer) Gold 5
5. Fizz (iDrone) Diamond 5

Our Team

1. Hecarim (McBallard) Silver 2
2. Syndra (Sweetest) Gold 3
3. Rakan (ideotech) Platinum 5
4. Kled (One Kick Guy) Gold 5
5. Draven (EnhancedArcane) Silver 5

This matchmaking has me pretty butt-hurt. According to Solo rank we are projected to lose 3 of 5 lanes with one tie. The losing lanes being Jungle, Mid, and Bot; the tie is in Top. To be more specific the Jungle loss is an 12 division spread, the Mid loss is an 8 division spread, and the Bot loss is a 10 division spread. Not only do i think that this kind of spread is complete bullsh*t, the matchmaking is atrocious.

But here is what really gets on my nerves. Flex queue is pinning me against diamond and platinum players, yet I am not allowed to queue with a platinum player (based on solo rank). How is this even remotely fair?

Maybe I'm over reacting but this game got me pretty heated while being stomped. No wait, that's an understatement; they beat us like a UFC fighter fighting a malnourished African child. That's before I checked each player's rank. I can't express how angry this game made me.
