Faris is my primary Thief because of the whole pirate thing. Also: Ninja, Hunter

Bartz is both my tank and melee specialist, including melee buffing, so Knight, Sorcerer, Samurai

Lenna gets magic, especially the non Black/White stuff: Summoner, Blue Mage and Geomancer

Galuf, in my mind he is always an old Knight-type donning his sword and armor to save the world one last time, but in the game he seemed to fit better as a caster the last time I played many years ago.

Krile, is a Dancer and Time Mage.

I think I may have made Krile my White Mage and Trainer well.
