Yes you can do whatever. As a lancer you will eventually become a dragoon at level 30 and you can't go back to a lancer. But you can swap between other jobs. For example, a conjurer becomes a white mage at level 30, ranger becomes a bard at 30 etc etc. Lancer and ranger and starting jobs like that are just like introductory stuff before the real job. I've seen ur posts before. YES you can play every job, YES you aren't stuck to anything in particular.
