Dynamic queues (again) Support complains (again)

OK, this might be a long one and it's my first time posting so i hope i don't mess the image up.

As you (hopefully) can tell by the image i'm plat 3 at the moment. (I was braum in the image).

So in this game we have me as a plat 3 support (unfortunately) who has to weigh up the two plat 5's in the other team. This is all good and dandy IF I WAS PLAYING A CARRY CHAMP! As you can tell they had Mundo and Panth as the plat players which is a whole 'nother story. I don't think i need to go into the differences between braum supp play style and mundo jung or panth top and their different possibilities to affect a game.

What the hell am i supposed to do as Braum - make my allies die slower? Do not come back with "a good support makes his team better". First of all - this argument is the same as saying i should try to support a tree or a rock in a war. "Hey man you run over there while i lay down some covering fire". Supporting a bad player is just a waste of time and will more likely result in you getting reported since you will die more trying to save them or trying to make plays.

Also, league chat is toxic almost regardless of what you say and it's kinda hard to have the time to type out everything since it's a high tempo game. I tried to tell Jhin to come closer so i could jump to him while being chased by Mundo and he replied "lol you really think we can kill Mundo?". Am i supposed to have a class before the game about how it should be played out?

I've been plat since season 4 but when season 6 hit i had a really hard time finding my way back up. Why? Because i main support. Or i used to, and that leads up to the point of my complaint:

** If you want people to play support, do something about the matchmaking**. Oh, i should play with a duo partner? Well hold on, lemme call my friend. I work night shifts and he works in the day but i think he has the time for one game, i mean screw work, amirite? Also, if i want to play support solo, my only reward shouldn't be having shorter queue times so i can feed faster.

The support role (and perhaps adc) is the most dependent on their team. Dynamic queues ruin games for supports constantly unless you play "ap supports" which is basically saying "fuck my team, i'm gonna carry". If that's the game you wanna have, sure, but then don't be wondering why no one wants to play real supports.

Well, i think i got it all out. Thanks for reading.

TL; DR - supporting is an upphill (sometimes vertical) battle in dynamic queues.
