Here's an idea I had

Fencer (Class) - > Red Mage (Job) Mid-line damage dealer, focuses on combining magic and swordplay into one, likely has some elemental buff spells?
Or
Fencer (Class) - > Blue mage (Job) Also Mid-line damage dealer, job abilities likely would have some variants based on your completion of the hunting log?

Fencer itself could be a class focusing on being able to hit the enemy rapidly though for less amounts of damage. Weapon of choice would be rapiers, sabers, and other various dueling blades. Likely unable to use shields, or possibly just light bucklers like how CNJ and THM plus WMG and BLM do. I see it having some decent parry and dodge rates, but possibly less VIT to balance that out for a Damage focused class?
