Names are not a very good description, just look at Sage, the old Sage is completely different gameplay-wise then its FF14 counterpart. So instead of names, I would like to say what mechanics I would like the jobs to have.

Tank: Using a spear and a shield, Valkire style that also wields Ice aspected magick.
Healer: I would like something like DNC, but instead of over-buffing your dance partner you apply heals through damage.
Melee: Something with a whip, probably close to how Ranjit plays.
Magic DPS: I would like something like a disease mage, applying dots and inflicting status effects on the enemy.
Ranged DPS: Something like a Blitzball player from FFX, I always thought it would be extremely funny to just hit my enemy in the face with a ball.
