Nu Mou do have a really interesting new job. Scholar. They can give random buffs to a target, and they can also deal damage to everyone.

Red mages are great for casting buffs, with both shell and protect available to them.

The bard class is great for a supplamentery ability. Soul etude is like a free Cura and esuna at the same time. Shame it's exclusive to (SPOILER)Hurdy

The new MP system makes half MP a must for you mages.

Beastmaster is only good for getting blue magic.

Seeq have some interesting jobs. the berserker can raise their evasion and do massive damage. Rangers set traps around the battlefield, and if you stop on one instead of an action the trap harms you. You should have the libra clan privilage when fighting an enemy ranger, because the traps can kill you vrey quickly. vikings can steal stuff and use thunder magic.

Gria only come with the hunter job, but they can fly. I got mine outside of Floirgis, so look there to find one.

This is a great game.
