I think Endwalker msq, trials, dungeons are actually pretty fine in terms of difficulty, I know on patch day when it was all new people seemed to have to learn somethings and the pulls were generally pretty hard as a tank/healer (if you didn't have a warrior) for a lot of the msq 6.0 dungeons, Not to say a lot of it is difficult but I don't really think it needs to be, it teaches you the basics its a decent challenge where you need to be aware, Although my main complaint is that tanks should be punished a bit more from taking a vunstack from failing a mech (increased damage on tanking classes specifically would be nice).

I wouldn't mind more midcore content though, I feel like theirs not a lot in-between dungeon level content and Savage content. It would be nice to have more things around slightly below EXT trial levels in general or a system to replay dungeons but made harder or something? like adding more damage and having less obvious mechs, I do feel like its too much of a Jump to get into EXT from normal duties I remember doing one of the SHB EXT and being told to watch a guide by a friend and all of it seemed intimidating at first.
