I've always played LNC as a DD that just so happened to be able to add a draining effect and lower enemy evasion (life surge) I rarely used speed surge.

We're still getting drain on attack abilities. And if you choose not to use the job there are tons of things you can cross class to enhance low group/soloability.

lnc has drains or increased attack if you arent tanking and still has increased tp generation

tons of cure things to be cross classed pug heal, mrd heal on your next ws, cures

MRD ws 6 will let you apply heavy form the back

pgl ws 2 will inflict blind from right or left



If that will help you still play support role. I'm not too bothered by it personally.
