Thief - This has been one of the basic starter classes in just about every FF game...idk why it was changed.

Black Mage - view thief

Dark Knight - awesome DD in almost every FF game that it was in (Since Cecil). Why not bring it back?

Corsair/Cannonist - amazing party support. With the ability to be just about anything (DD, buffer, side healer in FFXI) this class is one of the most diverse that I've seen and is one of the most fun that I've ever played.

Puppetmaster - Just an all around fun job in FFXI

Necromancer - it uses zombies...nuff said.
