Guess that Gunblade Job function.

[Reinfeld]

I think a gunblade job would be a DPS as people are pissed that every sword class is a tank so far.
At any rate it would be a very difficult job to create because of its mix of melee and ranged capabilities. For instance, an autoattack that adjusts itself based on the range of the enemy would be a horror to code. Unless the autoattack is a slash AND a shot.

If they just did it a'la FF8, I think they would just be melee with slashing attacks and the occasional point-blank shot. Then maybe they would have a single ranged GCD that would allow them to attack while getting into melee distance for their combos.
