I For One Don't Mind Dynamic Queue.
People always say that it is filled with toxic premades. Well Solo Queue had that problem too, just with less people in a premade. And even then, I have yet to come across a premade that was not fun as hell to play with. I hear all of these people saying that Dynamic Queue is full of premades that have made it impossible to climb. I won't lie, i get atleast 1 premade every other game, but you got that it Solo Queue aswell with people trying to boost themselves and a friend. As for the impossible to climb part, take a look at me, I have climbed from Bronze 3 to Silver 1 just this season. While that may not seem like a whole lot to most of you, keep in mind that I have been playing this game for less than a year at this point, and I am climbing just fine. I know when I say less than a year, most of you will be ready to say, "AHA! That's why you like Dynamic Queue, you never even experienced Solo Queue." And let me stop you right there, yes I did. I started back in August of 2015, and got into ranked within a month of playing the game. So I had about two months of experience with Solo Queue, and that was enough time to make my decision. I like Dynamic Queue, because I have found it more balanced in how it matches people together than Solo Queue ever did.
Thank You and Good Day!
EDIT: I am a solo player.
