That should be fundamentally a thing. After all elders scrolls just done 2 of their old dungeons into solo now as well as group made dungeons. But they put debuff or perks to the solo to add a increased chance for certain rewards while the easiest version without adding the debuffs gives a slight chance for a special reward set. This gives the ppl the option of going into it alone and raking their own time for a challenge or if they prefer do story level of the dungeon which is easy
