How To Unlock Dragoon

[archseraphus]

Dragoon need lvl 30 LNC, 15 marauder. I already have a lvl 20 pug that I played during phase 4.
The dragoon quest giver at lancer guild, you will need to clear all your class quest until the lvl 30 class quest.

Dragoon only can take skills from pug & mrd, and the skills are the same skills that you can take as a lancer

And I can confirm this is correct. MRD lvl 15 and LNC lvl 30 are the reqs that lock out the quest after you clear the lvl 30 LNC quest.
