They have always been more mage than fighter in every game (especially when they got Dual Cast in FFV). I actually find its AoE build up and execution to be fun and fairly fast.

What I do is Scatter until I have at least 45 of each mana (throwing in some Fleche between the cd of after a dualcast), then use Manafication, Corps-a-corps, Embolden, 3 Enchancted Moulinets, displacement, and then Contra Sixte.
