Well the first thing I like to do is unlock all the jobs. After that I got a lot of good jobs leveled up and I'm still at a decent level. Then I pick what I want my characters to be. I usually stick with Duel Wield unless I plan on making a magic user. I agree that this game is difficult when it comes to mastering all jobs, but that's not needed. If you do want to, like I do for some reason, get your characters in a figure 5 and hack the guy in the middle while he uses chakra.
