The cutoff works with some jobs better than others.
Many of them felt like they were at solid end points, and DRK's is all the better for that 80 capstone being the final installment.
Though it is a little funny that the RDM one was entirely "Let's look forward to more journeys soon!"

Overall?
No, I never really understood why the jobs had so much story in the first place and considering they burned out doing Hildebrand and had to take a break for an expac I'm sure they were itching to stop pumping out obligatory job quests.
