Class
Eorzea is home to myriad disciplines─professions that adventurers can take up. So as to be better prepared to brave the wilds, all adventurers begin their journey as either a Disciple of War—a master of arms who lives for the call of battle—or a Disciple of Magic—an erudite researcher of all things esoteric.

Experienced adventurers can take up other martial classes to diversify their skills. If you seek more peaceful pursuits, you may consider becoming a Disciple of the Land—one who gathers and harvests Eorzea’s natural resources—or a Disciple of the Hand—one who uses these resources to craft wares and turn a profit.
----------
Class is the basic tool that you first leveling up as. Class has the ability to equip other some other classes skills from Disciple of War and Magic.
Only some class abilities are unique to the class it self.
Flexible survival skill.
Good for soloing.

Jobs
Jobs refer to those martial paths that thrived in former times but have since fallen into disuse. Recent developments, however, have occasioned something of a revival in their popularity.

By achieving sufficient mastery in a certain class, adventurers will be able to begin undertaking the mantle of a related job. For instance, gladiators may rise up as paladins, stout swordsmen who shield comrades from harm; thaumaturges may aspire to become black mages, masters of offensive magic; while conjurers may find a new calling as white mages, masters of healing.

The foremost appeal of jobs is the unparalleled degree of specialization they offer. Their potential is best realized in party situations, where having well-defined roles is the key to success. There can be no doubt that jobs shine the brightest in the company of others.
----------
Jobs are a specialization of the Class. Giving a define roles in a Party. Althought will loose the ability to equip classes skills from other classes. Only able to equip the Jobs skill, main class and additional 2 class.
Eg. Paladin = Gladiator, Conjurer and Marauder. Paladin use gladiator main skills, with extra 5 Paladin unique skill, he can then add 5 more skill fomr Conjurer and Marauder class.

Class = Solo play
Job = Party Play.

Just think that Jobs are like specialization skill that is required in Party Play. Class are more of a versatile Solo Play.
