As a healer this is my list from easiest to pug to hardest:
Motherlode
Workshop
Rookery
Theater of Pain
Dark Flame Cleft
Cinderbrew Meadery
Priory of Sacred Flame (tie)
Floodgate (tie)
DFC was a hard one to place because it’s one of those dungeons that’s insanely easy with a good group but it can feel impossible if the mechanics aren’t handled well, particularly the bosses.
S1+S2 difficulty in tiers, easiest to hardest:
--------C tier--------
Motherlode
Mists of Tirna Scithe (S1)
Workshop
Ara Kara (S1)
Rookery
--------B tier--------
Necrotic Wake (S1)
Theater of Pain
Dark Flame Cleft
--------A tier--------
Siege of Boralus (S1)
Cinderbrew Meadery
Grim Batol (S1)
Dawnbreaker (S1)
Floodgate
Priory of Sacred Flame
--------S tier--------
Stonevault (S1)
City of Threads (S1)
One thing to say is that I played resto druid in both seasons and it currently feels quite a bit stronger now than it did last season which may be part of the reason I have so many S1 dungeons at the hardest difficulty. It also wasn’t easy to rank as many of these dungeons are similar in difficulty to me, though I feel strongly with my pick of COT as the hardest pug to heal. People might be surprised at me putting Grim Batol as the 6th hardest dungeon and while it had a high failure rate, strictly in terms of healing I didn’t think it was that bad. There was just a lot of kicks and stops to coordinate that often bricked keys.
