Personally, I've been very down on dungeon design for years so this comes to no surprise. Endwalker dungeons so far have been incredibly safe and in some ways just reductive with Lv83 dungeon being the worst (rivaling Ktisis, which ill get to in some other thread) instead of dissecting the dungeon like I usually do ill just go over why I hate going here so much
The Gates: First two corridors are VERY gate heavy possibly worse than Relict for how little sense it makes. Gates in general suck due to the devs severely underestimating the power of their mobs, and on paper it could've worked as a frantic rush to get mobs comming into the train in Phase 1, or rushing into the platform in phase 2....but no its all so safe and boring and none of the mobs have any distinction, no mechanics no cleaves no nothing just training dummies that are only relevant to the tank. Worse is that u have allies so DPS are even more useless and can go wait idly in the corner if they dont wanna play the game.
The undertuned mechanics/ Bosses: Zot was probably the best dungeon until the 90s roll in (not including Aitiascope) that being said idk why the mechanics lack a punch to push. First boss electric field is so ridiculously mild, as a sage I wait in there to gather addersting and the obligatory stack marker mech isnt super vital for 4 and can be 3 manned, as a tank I wait inside there to evade essentially all the mechs. Boss #2 is very boring in general but the switch mechanic is so offkey and very very forgiving, not useless tho as u can drown if you gte like 7 stacks or 8? and as a healer/dps the chakrams can murder you if you somehow get hit twice. and as for the final boss..
Waste of potential: Babil was the one dungeon/trial I was looking forward to do *spoilers* due to it being on the trailer, housing Anima and the source of all the Telophori. Finally doing it was a waste of creativity for how little they added to the place. Music and aesthetic once again will NOT save a boring dungeon. Anima is sadly the highlight of the dungeon but even then its sooooo lacking in mechanics and the 2nd phase barely touches anyone besides the ultimate. Anima has some unique mechanics more so than the last 2, but compared to the utter chaos that was the Magus sisters NONE of these minor mechanics weaved unto eachtoher at any point making the fight stagnate ( Example being the move Phantom pain and Lunar nail executing at the same time, or Boundless Pain and mega graviation)all that visual flare gone to utter waste and i think that makes it worse, far worse. Yea Ktisis is very boring, yes all dungeons in EW have similar malnourish issue but Babil being the turning point of the story suffering aswell is a let down.
