Out of curiousity who're you using and how're you using them? There are a lot of good characters without huge differences between them and a lot of opportunity for customization, so how're you playing?

Basch-Heavy armor, DD (spears for now, great swords later), techniks
Ashe-Light armor, sword and shield, white and protective magick
Fran-Magical armor, bow, white and black magick
