To be fair, you can change back to that other job at any time and you use it at the level you got it to, with all those skills, just like FFXI. And I've played the game for more than 200 hrs. You could say I like it a lot.
That sounds like a pretty standard job system then.
smh @ bebpo
Yeah, because I said something different

It's not like a standard job system because
Job system in most FFs -> you stay at the same level you were AND keep the spells learned in each job
Job system in DQVI/VII -> you drop to level 1 BUT you keep the spells learned in each job
Normally the idea of a job system is that you switch jobs to get useful spells and then build a character who has all the spells you want.
The main problem with DQIX is not keeping spells from old jobs, and the 2nd main problem is it takes FOREVER to get a lvl.1 character useful again. I changed jobs with 1 character at mid-game. I had them in my party with all the rest lvl.30 characters. They would die in 1 hit at first in every battle and couldn't do any damage, so I had them block and hoped they would survive. Once they got to about lvl.14 they could survive a few hits but still couldn't do any damage. This guy used to be one of my main damage dealers, so this whole time I'm down 1 major damage dealer. It took me
until almost the end of the main story for that guy to get near the levels of my other party members and finally become useful. Was not worth having a gimped team for the entire 2nd half of the game, just so I could have a guy with a better job for the last dungeon or two. And to unlock the "high class" jobs, you need to level 2 jobs to a certain point, so now repeat those 10-20 hours of getting him from lvl.1 to useful three times and there you have your high class character.
I thought the job system was trash
Aeana thought the job system was trash
duckroll thought the job system was trash
all for precisely these reasons. The game is trying to be an MMO so it's using an MMO job system that is insanely grind heavy and slow and time consuming and totally not appropriate for a single player 30 hour rpg.
