I have mixed feelings on this one, as the job quest lines in FF14 often were written terribly bad. Take the Warrior quests as example:
- Level 30: This is Curious Gorge. He is a Warrior. Warriors use the Beast Within, but he cannot control it yet.
- Level 35: He still cannot control the Beast Within.
- Level 40: He still cannot control the Beast Within.
- Level 45: He still cannot control the Beast Within.
- ...
- Level 70: We have some wonderful news - Curious Gorge is now in love! Oh, and he still cannot control the Beast Within.
Or Machinist: "Hello, I'm Stephanivien, the Machinist Guild leader. Machinists do a lot of fascinating things, but unfortunately I'm the worst leader in the world. Therefore you will spent 90% of your time as a Machinist searching for the other guild members that will constantly run away from my terrible lead."
Or Bard: "These here are Sanson and Guydelot - two guys that are constantly at each others throat, for whatever reason. Oh, and Sanson also is a moron that will fall for even the most obvious and childish trap. Your job is to babysit these guys for 30 levels. Have fun!"
Or take the Alacrans, an army of ruffians that is short of overtaking Uldah. Every other jobs fights them until level 30, and then they completely disappear out of the world. Why? Nobody knows. Fun fact: when you're new, the game throws a lot of names at you. I always confused "Alacran" and "Ascian", so the whole story made even less sense
And so on.
Job identity through different quest lines is a good thing in my book. But I honestly felt relieved when they got rid of them, as the majority was just very bad. And I liked the Shadowbringer role quests way more; unfortunately the 90 and 100 role quests were another drop in quality.
