What if two of them pops? You would have to withdraw one. You would get so many withdraw penalties too. The server would be looking to place you in TONS of locations cause of roulette. You could even double dip if you did roulette and regular queue at the same time. The duty finder server already gets confused as it is by single roulette queues and multi-selection queues. This would just crash the server. This idea sounds awful.
