The most Limited Content: Low-Level Dungeons

[Reinhardt_Azureheim]

but I doubt anyone will say getting Sastaha or Toto-Rak as a level 78 trying to get to Mt. Gulg is "fun" for their roulette when they're locked out of playing their job. Getting a low level dungeon essentially takes your job away from you because you lose all the skills that define the rotation.

If you are Lv71+ and you want a Lv71+ dungeon, then the solution is to queue for said dungeons, not Roulettes. Old content gets facerolled as is due to gearsync and pre-50 potency changes from SHB release and I believe one can put up with playing with a basic kit when doing a daily roulette dungeon for 15min if they roll a low-end dungeon. If you can't deal with "not having fun" for a while, don't do it.
