Dragons and lances don't go together? I mean, a lance is meant to make it easier to kill a dragon. I guess you are mixing up FF with WoW, where Dragonknight (Dragoon) and lances are bound together by choice of job.
Dracthyr's options are great as they are. Just like shamans, but with swords and no shields (If I recall).

He's right @DragonGuard
The main stats on the weapon, if you cannot use said stat, just grays out. So, if you pick up a strength sword, and you use int as main, then you just have a sword with secondary stats and stamina.
