Job quests where it says here is crystal here you go doesn't do it for me. Reaper doesn't tell you anything about Reapers just Garleans and you have no lore regarding your pact at all. You just fool around with Garlean Gangsters.

Your Sage Trainer isn't even a Sage. And I think the Sage capstone quest is the only good one and I'm pretty sure it doesn't go indepth about how Sage's work.

You got some jobs that are amazing like DRK while you get others like PLD which is more Gladiator then PLD.

They probably ran out of ideas with all the jobs.

I think DRK and BLU are my favorite job questlines.

You get Lore on where BLU's originated and you learn that pretty much anyone can be a BLU and that the Job Crystals are all fakes and that Derplander the legendary Gilseller is your class trainer.

I also have fond memories of the MCH questline being a bit of Pirate but also your gadgets and guns being used for Ishgard.

Plus with Role quests to unlock a specific quest they force you to level jobs you don't want to level so it's kinda garbage IMO.

Edit: I should also say that Estinien got to where he is today because of the DRG job questline so...
