Opinion: Duo Queue should be made to flex

I'm making an argument here to lay out what I consider facts, and have debate. I don't need to die on this hill.

The main argument here concerns itself with relative power. Two people in solo queue are judged equally to one person joining solo queue. For obvious reasons, this is a wild imbalance in terms of skills reflection. Furthermore, two people can verbally abuse or troll/grief someone in game substantially and it should be removed. Duo's also tend to be like-minded. They show up to win/have fun/be toxic together. That's a considerable disadvantage for one team with a duo compared to a team without. To clarify that point, if we're all individual, we get 5 mindsets. A duo reduces that to 1.

Most people recommend climbing as duo. That's not a mistake. It's because it's a considerable advantage. I'm not entirely sure how this option is available when we have Flex Ranked and it tends to be 3's and 2's (again, with 4s blocked).

To be less formal about it, duo queue never seems to provide a benefit to the team more than 5 individuals and I think it's stupid they're given the same review a solo person is.
