Can we talk about duo ques?

I think duo ques are bullshit. The reason why is because to me it's unfair, if I'm in solo que with very limited way of commutating with my teammates how is it fair as a player who have explain everything in pings. If I could talk to my teammates with my voice I do, but I have no mic and I would just want to climb on my own. How is it fair that they will climb faster then me for communicating with each other when I need to roll the dice every que if my teammates will listen to me. For example asking my ADC to stop spilt push and just group up with the team. I get it you want to play with your friends I get it but we have flex que for that; isn't that the whole reason why we have two different ques? When every I play against a duo que I feel like I'm at a disadvantage, I get this feeling that the only reason why they are beating me is because they have something I lack. It's not like "oh they have better teammates then me so that why they are beating me," no it's more like they can do something I can't do. So that's what I think when it comes to duo ques.
