My problem with the 6.0 MSQ was Labyrinthos was a filler zone, Thavnair part 1 was find the macguffin, part 2 was save the baby but I am ok with that, Garlemald was fine, Moon after Zodiark felt like filler, Elpis was fine for me though I was annoyed at how obvious it was that Meteion was the big bad after revealing her voice on the moon, and Ultima Thule was contrived and I hated how obvious of a bait it was with everyone "dying". Shadowbringers zones had their filler parts but the zones to me felt more meaningful to the story's progression.
