Which next three jobs would you like to see for the next expansion? I'm going with:
  • DPS - Samurai
  • DPS - Beastmaster
  • Healer - Chemist

Noteable mentions:
  • Red Mage
  • Blue Mage
  • Geomancer

And lastly I would absolutely appreciate it if Square-Enix would add Ranger as a non-support, full ranged DPS job crystal to the Archer class that plays with the same mobility Bard did before the Bard-Mage thing. It's main weapon would change to crossbow instead of bow. Actually, scratch that. Introduce it as a separate job that uses the crossbow as it's main weapon.

As for Red Mage, Blue Mage and Geomancer. I am not too sure which roles those jobs would play. I can see Red Mage use a mixture of physical and magical DPS with some healing involved. Blue mage would seem like a DPS with a wide variety of monster skills available to them and Geomancer would likely be a magical ranged DPS.
