Hey, everyone.
Decided to share my opinion (damage dealer, atm M+12 keys 4/8, devastation evoker) and read yours interestingly.
The easiest: Ara-Kara City of Echoes, The Dawnbreaker, Siege of Boralus (not sure which one is the most),
hardest: Stonevault.
My tier list:
S tier:
A tier: Stonevault
B tier: Grim Batol, Mists of Tirna Scithe
C tier: The Necrotic Wake, City of Threads
D tier: Ara-Kara City of Echoes, The Dawnbreaker, Siege of Boralus
COT is probably the hardest key for many at this point in the season. Everything else is pretty reasonable now even NW and SV
I’m surprised Mists is so high up on the list.
Tier lists are probably very subjective.
In my opinion, it’s a very simple dungeon, with minor difficulties only on the last boss, maybe it’s a matter of the class and specialization in which I play.
My easiest to hardest M+ dungeon tier:
S: Dawnbreaker
A: Ara-Kara and Mists
B: Siege of Boralus
C: Necrotic Wake and Stonevault
D: Grim Batol
F: City of Threads (it’s deserved to be in top 10 worst dungeons of all time in my opinion)
Hmm, what exactly makes it hardest one for you? Which bosses, packs, mechanics?
The bosses in CoT are +2-3 key levels higher then all the other dungeons imho.
Boss 1 is a pain. The others are throughput checks.
Oh boy, where I start with that. Like Caithyra said, the bosses in CoT are 2-3 key levels harder than all the other dungeon bosses. The first boss have a tank buster every 12 seconds, you know how bad it is. 2nd boss is awful designed fight and it’s a long fight. 3rd boss is clearly overtuned with tank buster, raid wide damage, healing absorb and area of denial. The last boss does mechanics like every 10 seconds, that boss is a healing and defensive check. Oh, I forgot I have to mention the casters literally machine gun web bolts.
No one want to run City of Threads and pretend City of Threads is not exist at all this season

Based on the data and my experience (Easiest to Hardest):
City of Threads is definitely the hardest imo, the damage output, defensives, and healing required on the last boss on even a 14 and 13 are insane.
Regarding Grim Batol, I think once you start cutting out the double add pack before third boss, and pulling some trash into second boss gb becomes a much easier key overall. The timer is definitely tight though, and the risk of stupid wipes to butt pulls in this key is very VERY high.
Last boss in NW also becomes quite difficult past 12 imo.
always with the numbers and stats to back it up! love it 
easiest is mists in my opinion (probably because i have prior experience in here and know it by heart)… the hardest is city of threads, cuz it just sucks and i don’t want to be there.
Stonevault is my favorite this season because the fights are interesting, and it tests decision making skills 
I think it really depends on key level and group comp/members. If your healer is weak, CoT bosses are going to be a nightmare. If your DPS are braindead, then Stonevault has the harder bosses. Grim Batol has the nastiest trash, so there’s a lot of pressure on the tank and as key levels scale up, it becomes worse (though that’s been toned down with the fixes today).
Yeah Stonevault was easily my favorite dungeon in terms of pulls and mechanics.
Enda feels like it lasts too long.
