It's not a mage at all, you don't cast any magic spells.

Here's a different perspective to look at Wanderer's Minuet: It's not just one song you play and it buffs everything, it turns each skill into it's own little song! How much more bard like can it get? It's almost as if you never run out of songs!
And each of those little songs is a utility - the utility of contributing DPS to the group that isn't complete shit.

If this is far too much like bard for you, then simply remove your job crystal, because I believe you are looking for archer.
