Flex Queue matchmaking should take Solo Queue rank in account, and only let 5 mans play vs 5 mans

I just played my D5 Flex Promo as soloplayer. My enemy had a full 5 man team. The Solo queue ranks of my team were: D5, D5, P2, P3, G2, meanwhile the enemies were D5, D5, D3, D3, D2

So even if those were all solo players, the enemies would already have an insane advantage in terms of individual skills, but the fact that i have to play as SOLOPLAYER vs a freaking 5 Man team that is also by far higher ranked than my team is absolutely ridiculous and whoever made this system should be fired as soon as possible. It's ZERO fun to play a game, where u have virtually no chance to win from the start of the game, no matter how well you play. Escpecially when this is a Promo game that decides if you rank up or not. Obviously they won every lane and then outmacro'd us in every single way due to the insane advantage of the communication.

SO PLEASE. Put 5 mans against other 5 mans, and fix the mmr. I can understand i have to play vs duo and triple queues, im fine with that, its winable since i usually have a duo or triple too, but its NOT fine to play vs a 5 man on my own.
