I dunno, a buddy of mine was dragoon(Kaini) and was constantly being asked into Japanese parties. Japanese know what works and what doesn't and never mess around so must have been something useful.
You didn't know much Japanese then. Not to say they didn't have great players, because they did, but they had an overwhelming amount of terrible players--especially on the endgame scene.
Anyway, pre-Drakesbane, Dragoon was pretty awful. It's weaponskills were not great generally speaking, and the job was horrendously attack-starved.
It was decent for EXP parties though especially enemies weak to pierce, as fodder enemies generally didn't have much defence, and Dragoon has great accuracy through it's traits. Come endgame though, it's lack of attack, especially through the equipment it had access to, really showed. Wasn't until the introduction of Salvage and the Ares' equipment that it picked up somewhat, but then later on came Drakesbane and it improved significantly. Too bad that was quite late era for the latter, though. It always had Angon, so it wasn't completely worthless against the high-end enemies/slimes etc.
Enough of that though, I have no idea how DRG performs on Nasomi, they're quite a rarity. Many of the damage formulas though are messed up pretty bad, but that could be a good thing for DRG, or it could make the job worse than it ever was /shrug.
