Not on goblin, so I can't offer much assistance... Buut, assuming you stunted leveling stems from a lack of quests in your area (story makes for extremely fast levels on one's first class) make sure to try and make use of FATES and side quests to speed up your road to 15 and your job's soul stone. You miiiight be able to queue for isolated guildhests and make use of first time exp bonuses, but I think the roulette is locked until 15 or 16. All in all, after one's first class, the first fifteen are usually going to be the most slow going levels. Kinda of counter intuitive, but that's been my experience.
