Duty Roulette - low level - same dungeons???

[Simaril]

Done it every day for the past week and have only gotten Sastasha. This is bullshit, especially when every other person in the group is relic geared (and I'm a level 34 WHM, 50 Relic Bard or 50 Relic PLD....whichever I feel like playing at the time...)

This is bad. I've completely lost interest in Roulette and stopped using it because of this. I seemed like a good tool, but placing an entirely high level party in a the same low level dungeons kills motivation to use it.
