I'm currently just past the Water Crystal stage, so I have access to Dark Knights and Vikings and stuff, but not Ninjas and Sages etc.

What I'm working with right now is a Knight, Thief, WM and BM. What I want to do later on is move onto a DK, Dragoon, Devout and Ninja combo, seeing as elemental weaknesses become kinda irrelevant later on (I hear). This is my first time through and I'm just wondering if that sounds like a good plan. Don't know equipment well enough to plan far ahead, though I'm thinking Blood weapons in one hand for both the Dragoon and DK.
