Ranked solo?

I'm trying to figure out why i would even queue up for dynamic with the introduction of ranked solo. What benefits will there be? A more enjoyable ranked? yeah...sure that's the only thing. But with solo being introduced queue times will go up for dynamic if you play with 3-4 people because the people to fill the spots will be playing solo. If you're going to make solo a seperate ranked you might as well make it solo/duo again to make it enjoyable.
