There is a reason SE has not done a CS heavy multiplayer duty since these 2 from ARR. At this point I do not expect them to make any adjustments to it. The roulette was made an option just so players could queue it outside of pre-making a party in PF for it though at the time PF wasn't across data center so you had to find 7 people on your world that wanted to do it because almost no one would queue them as a single duty.
