Right now, you have a short sword dps, a thin sword dps, a standard sword tank, a biggest sword tank, and a curved big sword dps. When you add a gun-sword tank to the mix and are expected to design weapons that are thematically part of the same set yet visually distinct, I'm afraid that subtlety has to go out the window. Look! This is indeed a GNB sword and not the PLD (vanilla), RDM (thin), DRK (big), SAM (curve) or NIN (smol) version. It has lots of technology! It is very very gun! (but not too gun, because that would be MCH)

Wait until someone gets Zidane's double-bladed sword as a job weapon. Then all bets are off.
