I just recently found out that a bunch of Jobs have a level 80 quest that is designed to give kind of a final farewell to those stories as the game moved on to role quests, and they are just marked as normal yellow quests, many of them in out of the way places you wouldn't normally visit.

I understand that they don't give any essential reward, and maybe that is why they don't pop-up under the MSQ, but it would be nice if they at least had Blue markers to make them more noticeable.
