Please understand what dynamic means. It is not the same as team or opposite of solo
It's something of a pet peeve of mine to watch people thinking dynamic queue equals the current dynamic team queue. With all the solo-queue threads popping up, I keep seeing people say that solo and dynamic can't exist together. But if solo-queue does come, IT WILL BE A DYNAMIC QUEUE.
Dynamic refers to the current type of draft mode where you can choose 2 positions and the system "dynamicly" forges teams together based preferences rather than the old queue which just used the static system of jam 2 teams of 5 together and let them sort it out.
Types of queues exclusive to dynamic queue are the old static draft, the now dead team builder, and blind pick. Solo and team belongs to a different system of classification.
