So I went on a break after getting to this point in the game (spoilers) (SPOILER) My party got to the new continent and has their ship grounded by a golden chain

with my parties current character levels/job levels, am I in a good place? I heard when possible its best to grind job levels in ur on goblins.
also how long until I get the chance to go back to ur for this?

also for some reason my thief has the highest job level, i mean way past the others, and i just recently turned one into a knight, that makes sense for that character.
but my white mage and black mage have been that job ever since it was available

posting screenies of my characters status pages to help with this
