Well im kinda feeling the same to be honest. Especially older content where dungeons/trials are getting easier and easier each expansion/patch with higher ilv gear (the syncing in this game is not good).

i understand that there are people that just want to enjoy the story and dont want to face a hard content to continue the story, especially disable people since the devs want "Everyone" to be able to play it without a problem. More people = more money = more content

I do feel like the difficulty is increasing each expansion, but only until shadowbringers. I think they only do difficult duties for side stuff like AR, Trials, and normal raid. But with endwalker, i feel like the difficulty for normal content isn't as hard as previous expansions. Ivalice is my favorite AR because of the difficulty, i really like first 2 Nier AR because of the difficulty. But the 3rd nier raid and the twelve gods 1st AR is pretty disapointing because of how simple the mechanics are.
