How about some new / unique to ffxiv classes? I Was thinking along the lines of like

Pirate / Swashbuckler.
]Dual Wields a Sword and a Gun. (Might use both str and dex to determine damage as well as offer some utility) Originating from Limsa.
A Hunter
Originating from Dravania. Uses Pet's in combat. May start with a chocobo and eventually get a Dragon.
Since I'm personally tired of Physical Melee DPS how about
BattleMage
A Mage who focuses more on the upkeep of their body along with the manipulation of magic. Probably a class that stems from Manderville lol.
