I see it a little bit like you. I see it as a melee DD with support/debuffs. Using rapiers or epees or scimitars with En-spells. Ex: En-Fire on weapons to give a bonus damage. Spell wise, it would be Slow, Haste, Gravity, Cure.
A little bit like FFXI but with more melee support. It could have buff spells for damage and accuracy.

Happy Hunting!
