When I heard that they were wanting to think of new jobs for 7.0, I got to thinking of some like Chemist and Time Mage, but those job would mainly fit healer roles... Since it probably needs balance, it would have to be a ranged DPS and caster DPS.
So I got to thinking of a ranged DPS that would fit in and the one that came to mind would be a corsair.
There is already a few enemies in game that use both a gun and blade and that gave inspiration to this~ That and the uniqueness is enough to not collide or feel to similar to other jobs.
I've left out cooldowns, durations and potency mainly because I wouldn't quite know a good balance.
Of course the melee combo would be stronger than the gun combo, but the combo boost would make up for it and make it balanced to use the gun combos as well.
The full details is in the next post since the original was too big.
