Is there a hint of a future job according to this character (spoilers)?

Did YOU pay attention? They literally tell you in the GNB questline that the weapons garleans use are NOT gunblades. They're more like giant bayonets to their carbine rifles, rather than a sword with a gun on it.

Regardless what lore they come up with(I personally thought that lore explanation was roundabout BS personally), gunblades have been around since FF8 and it's clear they were riffing on that look, and also clear the FFXIV players wanted gunblades because of that.
