Well, they answered that already. Honestly it's probably the level, sounds like they were expecting quests the same level as DoW/M job quests and it's not. It's just not clear if they'd done the 3.0 lv 50 quest or not, but they're all with the same npc so they're likely done, unless they'd done the 50 quest before 3.0 and are just looking in ishgard for the next one.
