Ah. Another "get rid of it because ... cutscenes" thread.

The MSQ Roulette serves two important purposes:

1. It is the quickest method for leveling past 50 for time invested, because the XP is commensurate with the time. You can, for instance, gain almost enough XP as a new level-89 job to allow you to reach level 90. It is much lower at lower levels, but the premise is still the same.

2. It is one of the easiest method for receiving Mog Treasure tomestones, as it grants more of them per instance. Want something that requires 50 tomestones? Run 8 instances of MSQ roulette vs. 16 for those instances that grant 2 or 3 tomestones each.

The real truth is most players don't need to queue for the MSQ Roulette at all. There are plenty of other ways to obtain XP.
