Technically there are already 2 dps queues, it just doesn't show it. Ranged and melee are split.
You can queue as a melee now, get 1 wait time and role waiting list number. Queue as ranged and you will have a longer wait time and a higher number, at least in my experience.
Same thing shows if you queue in a party with a friend, 1 melee 1 ranged. You will have different wait times and role waiting list numbers for roulettes.
It just doesn't require one of each, and will accept 2 melee or 2 ranged for a duty to not hold up queues.
