I think what DRK needs is something that gives them the ability to instant cast (perhaps at 0 MP even) an elemental nuke.

Like a job ability on a recast timer that gives the bonus to one spell. Or a job trait that procs it, like how Zanshin works.

I've had my uses for elemental magic at times, but right now the damage is very pathetic to use anything other than a scythe, and it would be nice to instantly cast occasionally for somewhat respectable damage. Not saying 5k or anything, but the occasional 800 dmg nuke would be nice.
