Question about New Jobs

[Fear]

I don't understand why people can't grasp the most basic principle of the job system.

Jobs gain abilities and possibly other unique characteristics through quests, they DO NOT level up. It has been said over and over and over again that jobs will not have their own experience levels and any experience earned while playing a job will go straight to that respective class.

Read my post again, I said they level up WITH QUESTS

From the past posts it seems that jobs will unlock at Lv30 and you'll have to complete quests to level them up to the same as the class is so 50 GLA would unlock 30 PLD then you'll complete a series of quests to gain AF and higher level

correct would be "so 50 GLA would unlock 50 PLD"

No, because they said your job will be capped untill you progress through quests and gain higher level limits / Artifact armour.

Your Job won't have any level. It will have the stats (maybe a slight boost? Maybe its own? But capped by the Class level) of the related Class level. If you are Gladiator 30, you will be able to switch to PLD but it will keep your Gladiator stats (maybe a slight boost? Maybe its own? But capped by the Class level). What will change is you will lose your X-Actions and you will be able to equip new Action(s) granted by the Job.
Then, as you level your Class, you will unlock quests from level 30 to level 50 from which you will be able to learn your next Job Actions.
