I don't think the dungeons should be nerfed but I do think they need to be given their own roulette category. Getting a high level roulette for Haukke HM or Copperbell HM usually results in wasted time as at least 1 of those 4 players probably can't cut it, same goes for Pharos but imo that's because the first boss is rather overtuned and genuinely needs a tweak down.
