How is dynamic q more competitive than solo q ?

"We believe that dynamic queue is closer to representing a healthy, competitive landscape in League of Legends than solo/duo queue."

I really don't understand how is it possible for them to think that. I don't play ranked anymore, only games not to decay because I have no motivation or will to play against premades/boosters. And even with just 1 game a month, I see everything what's wrong with dynamic. Last game I played was in plat 4 vs. a diamond 2 who duoed with a plat 5 dude that was gold for 2 years and now is magically plat. Hmmm, I really don't know how that happened, right. The ranked ladder is just complete bullshit. Every streamer I tune into wants solo q, same as pros from what I saw and if they don't represent the competitive side of the community, Idk who does. So if all the pros and challenger players want solo q, I don't see what's the reasoning behind thinking that dynamic is more competitive than solo q. I felt that way ever since I read about dynamic q. If they really think dynamic q is better, then Idk why 2 of my friends quit LoL and went to cs go, or why on my friends list almost nobody is playing ranked. I never see anyone trying to grind away ranked to become better. This is just a huge disappointment for me, I still love the game and my champions but I won't succumb and play dynamic after waiting for months on solo q. I was diamond last season btw and had huge hopes of reaching master/challenger this time but all the motivation went away. I'll just play normals until I get tired of them and feel disappointed every time I click on normal blind pick instead of ranked.
