I tried to use jobs that were handy and made my characters look cool
I used these primaraly:
Bartz - Sorcerer (Mystic Knight) With 2-Handed Ability (to equip Excalibur)
Reina - Lancer (Dragoon) With White Lv. 6 (to use Arise after surviving heavy atatck using Jump)
Krile - White Mage With Time Lv. 6 (for Meteo and Quick)
Faris - Ninja With Sword Lv. 6 (For heavy damage)
I liked this combo, it made me look cool, and it made me strong
My overall favorite was the Mistic Knight, becuz of the changing of elements combined with the power of a sword.
