Call me crazy, but what if the new job is Beastmaster? The obvious answers seems to be Dancer, Samurai, or Blue Mage, but as Astrologian seems to incorporate elements of Time Mage, what if we got Beast Master with a slight affinity to Blue Mage?

Traditionally a DPS class, what if FFXIV put it into the Tanking Role, and had the player Transform into a Beast to tank, similar to various stances?

I know this is coming pretty much out of nowhere, but hey, speculation is fun, right?

As for a weapon, I wouldn't mind seeing a Whip as a weapon, although if the character transforms into a beast I can't see how the weapon would matter much. Maybe a talisman? Could be intriguing if the standard form (stance) for DPS is your character's natural state, and the tanking form (stance) is a transformation that varies based upon your weapon. That could offer a wider variety of option of transformations. Everything from Coerls and Eftmaws and Elbasts to Tigers, Bears, and Wolves.
