Dynamic Queue Should Allow A Single Role to Be Chosen

I don't know how many people will share my opinion, but I know that my friends and I are all in agreement.

Regarding the Dynamic Queue system, I truly feel that Riot needs to make changes, namely allow us to call a single role. As a Mid main, I understand that I play a popular role, so it's no surprise that I am getting my Secondary role the vast majority of the time. What I do NOT understand is why I cannot simply call Mid and wait for a longer queue time. I would not mind that additional time if it meant ACTUALLY getting the role that I want to play. After all, isn't that the point of the Dynamic Queue? Isn't that the point of telling the system what I want to play? In plenty of MMORPGs, you have to wait longer in dungeon queues when you play a DPS class. That is understood and accepted. Why not in League?

I have been playing League since Season 1, and never before have I gotten my preferred role this infrequently. I get Mid maaaybe a third of the time, and when I do get it it's typically because I'm with a 4 or 5 man premade. I truly feel that this is negatively impacting my Ranked performance. Why should I be punished simply because I play a popular role?

TL;DR The DQ should allow you to choose a single role and wait however long it takes, just like in MMORPGs for dungeons.
