How did you manage to screw up dynamic queue?

I just returned to this game after a short break only to be disappoint by riot again. How in the world does it make sense that you put a player in placements well below the skill level they have achieved through multiple seasons and then auto select them for support? In the past I understood picking mid/bot would mean longer queues, but that also gave me the ability to carry the game. Why would you ever have ranked games auto select players for a role they have no interest in playing?? If the answer to that question is faster queue times, then I'm sorry, you put zero thought into it. If people were complaining about long queues when they had THEIR OWN CHOICE of lane/role, then it was their own fault. They could have picked support and received a much faster queue time. Forcing someone into a role to speed up queue times for everybody is a travesty. Whats the point of even being able to pick your role when every other game you're forced into support? I have played since beta, own all champs, almost all runes put a lot of money and time into this game and you (riot) constantly are ruining what used to be a fun and engaging experience. I've already uninstalled the game again because it is absolutely stupid that I lose games that I could have easily carried but get forced into a role that I have no interest in playing when I would have rather just waited the extra 5-10 mins to play a role in a game that I actually want to play.

I have put 0 effort into searching if this is a common complaint or not, or whether this has been answered before and probably won't check back up on this post. I just felt it was worth my time to write here and let you know that you have really been slowly destroying your game over the past few years.
