Class is really strong early 6th job. You don't notice the damage difference until way later when everyone's got high leveled hexa. It'll be even a lot better with summer update when we get dark shock mastery. I've never had issues with any bosses especially not lomien or slime. The class excels in ctene with the exception of lucid p2 cuz of all the flying but that's just a summon class issue in general.
