I really strongly agree with most of your takes except for TJS. For me it's a mostly bad dungeon, but I would still only put it in C as it doesn't compare to SBG. Trash-wise the only good trash is between the 2nd and the 3rd boss (excluding the twins) and everything else is just not interesting. There is more trash variety in that short part than in the entire rest of the dungeon combined. For bosses, I agree that they improved Wise Mari for M+ and I won't deny that I have died to that beam a few times particularly with affixes, but the boss is not challenging. You die because you are stupid or because of the affixes but it is inherently simple - It feels like it is missing a mechanic to me. 2nd Boss is fun to heal for me, but there is also not really that much happening - you swap and juggle the buff. What I would have wished for here is an extra mechanic that changes depending of whether Strife or Peril are lower, that maybe gets supercharged when you immune them. You said that the 3rd boss is mechanically difficult, but that is only true for tanks. For healer it's literally only P2 and for DPS there is nothing. For me the last boss has the right level of being difficult but I feel that the bounds of reality feel so disconnected from the boss and make this fight too long. Instead of killing them for the boss not to heal maybe they should have made it so you can do as much damage as you want to them while they are up and it also damages the boss. So that you can juggle between CCing them for safety or keeping them on the boss for efficiency.
