What solo queuers do not realize about Dynamic Queue. . . .
What solo queuers do not realize about Dynamic Queue is that Dynamic Queue relies entirely on solo queuers to function.
How?
Dynamic queue searches out solo players to fill in the gaps on premade teams. This way four-man premades can play together since the system finds a solo player to fill in that last slot, and three-man premades will get either two solos or a duo to fill in.
So what if there were no solo queuers for the system to fill in the empty slots with? What would happen?
If there were no solo queuers to fill in the empty slots, four-man premades would be completely unable to queue. Three-man premades would be forced to wait for a duo to become available, while five-man premades would have to wait for the enemy team to match together triple and duo premades if there wasn't another five-man available.
Four-man premades would cease to exist since they would be stuck in queue forever with no solos to fill in the last slot, while queue times for duo, triple, and five-man premades would increase to a point that people would get sick of waiting for matches and stop playing ranked.
To put it simply, Dynamic Queue relies on solo queuers to function, and without them it would collapse under its own weight.
TL;DR If solo players really wanted to get rid of Dynamic Queue they would stop playing ranked and let the system die.
