The point I’m trying to make, though is that these are all conscious decisions. For example, they didn’t have to make Dark Knights fill the lore role that they do, they could have plopped them in Gridania and said they practice some ancient Gelmorran swordcraft or whatever. On account of the whole game being a work of fiction, there is nothing a priori that says jobs have to tie into the lore of an expansion area. SE decided that Dark Knights are an Ishgard thing, but they aren’t an Ishgard thing by default.
While we can’t be undo that decision for HW’s jobs, any new jobs in 4.0. don’t have to follow the same path. The devs write the lore for the jobs just as much as they write the lore for the MSQ, so they are more than capable of writing MSQ-independent lore for new jobs.
