Labyrinth and Syrcus Tower...

20 minutes are a pretty common Queue time for basically everything on my DC as DPS, so I don't see the issue, aside from people being spoiled by insta queues.

That's fine you don't see an issue. If you think it is fine for you, then that is your own personal belief. However, there are other players (myself being one) that would enjoy the variety that comes from using a system that carries "roulette" in the name rather than seeing the same two instances repeatedly since the other group wants to cheese the system. You and I have clearly two different perspectives on the matter, and right now, the way I would like the system to be used is severely undermined by those who share your sentiments. I don't think it is particularly fair that one group gets to rig the system in their favor to get what they want while the other group is left being disappointed by the lack of variety.

As someone suggested earlier in the discussion, fixing the rewards would be one way to make it worthwhile to players. There is very much an imbalance in the rewards considering how much easier it is to do the ARR raids rather than the SB ones. I don't see why there shouldn't be a discussion to try and resolve the issue to make it satisfying for both camps.
