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

Also your incorrect gunblades have been a imperial thing since reborn Guise and many of the imperial troops walk around with gunblades. DO you even pay attention to their weapons?

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.
