Dynamic Queue Creates Less Diversity/Experimentation

Ever since dynamic queue debuted, I feel like a lot of people started to only play their two best roles, even in normals. I think that dynamic queue might create less diversity for a new player to explore their options, as they will play two roles, and believe they achieve the most by playing those roles, and will never try to play the other two roles that are available. For example, in blind pick, we would many times not get the lane we want, forcing us to try other lanes/roles. This allowed me, personally, to find the role I am best at. I think that with dynamic queue, a lot of that diversity and experimentation will disappear.
