sure there's the job-specific license board but it also sucks because i hear once you choose one you can't go back. you can be any job you want in the original anyway, it's just not spoon-fed to you.
Pretty much, though the 'you can be any job' has it negative drawbacks. If I had to choose between the Zodiac Jobs that you have to stick with... or the 'any job' [aka jack of all trades], I'd choose the former. I like an RPG where I want to replay again to experiment with other job classes which have all their perks and weaknesses.
And that's pretty much the biggest feature that would make me return to FFXII.
