There was nothing innately challenging or difficult about this quest it was entirely made up of artificial difficulty and completely just a lesson in patience there was no skill required to get it done just patience and maybe some luck depending on how you think about it.

Being able to click a pvp combo, a mitigation button, a damage buff button, and a potion does not take skill nor is it challenging.
Being able to find potions does not take skill & is not challenging it's merely a test of patience.
Dodging mob aggro does not take skill, is not challenging, and is not fun because you don't know if the mobs are LoS or sound based or both.

There was nothing difficult or challenging about the quest it was just needlessly unfun and filled with artificial difficulty.

I'm playing FFXIV not Thief, not Deus Ex Machina, not Dishonored, I'm playing FFXIV if I wanted to play a stealth game that requires skill and is challenging I would play one of those games.

Difficult and challenging content does not require you to be under a handicap.

The difficult and challenging content being requested by the community can stand on its own merit, it requires you to rise up to the challenge rather than being dragged down to its level.

Do not conflate the two.

There are plenty of needlessly unfun mechanics in MSQ instances that require you to restart simply because you it was your first time doing it or there was a gimmick and this is just another one.
