Jobs

The job system - that series-defining trademark - will be implemented in FINAL FANTASY XIV (details such as specific jobs TBA). Quests to unlock each job will become available once you have reached a certain rank in the corresponding class.
Rather than being advanced versions of classes, we would like players to think of jobs as specialized playing styles optimized for partying. While playing as a particular job will render you unable to equip certain actions of other classes, you will be compensated with access to exclusive actions, which can be acquired through quests.

In practice, players will find the existing classes effective when playing solo or in certain party setups. Jobs, however, will shine in party situations where specific skill sets are demanded. Now, you didn’t hear this from me, but there are also rumors circulating that quests for obtaining job-exclusive equipment are also in the pipes.
We at the development team are currently hard at work on the job system, and expect to have details to share with you soon.
I know its a long way off, but I wanted to get this request out there so enough people have a chance to read it. How will I know which class to level in preparation for the job I want to play in the future? Most classic FF jobs I can guess at. However will ninja be gladiator or pugilist? How about thief? Some jobs are ambiguous as to which category they will fall under.

If you solidify this information before you program the changes, I am requesting you post it to give current players a goal to level that class.
