Solo flawless discussion

What do you guys think the hardest solo flawless dungeons are? Here is my list (hardest to easiest). Keep in mind I am a Titan main so I understand lists are going to vary significantly for other mains. I.e hunters spamming blade barrage/ golden gun. Warlocks spamming sunbracers and well. What is your order?

  1. Ghosts of the deep (big health pools, final boss mechanic slog, butterflies)
  2. Vespers host (mechanics and lightning are more of a threat)
  3. Warlords ruin (big health pools, insane amount of ads during final boss, 2nd boss is demoralizingly slow)
  4. Duality and spire of the watcher are tied for me… I really can’t decide which one’s harder. Putting the bugs aside, the first two encounters are cake with the right build… the last encounter is pretty rough during dps phase due to the psions and the bell mechanic … for spire of the watcher the second encounter can be tricky as a titan for dps… the last encounter is comparable to the last encounter in duality… in spire you get blown up from supplicants, and the boss does a lot of damage…. I’d say these dungeons are pretty equal
  5. Prophecy
  6. Grasp of avarice
  7. Pit of heresy
  8. Shattered throne
