i think its mostly just based on what jobs oyu havein your party/alliance, Me and my husband when into dyna windy today got 47 Whites total, proced 95% of the time, either being a DRG WS (alot of them were vorpal thrust) THF WS (alot of the time it was shark bite) or DRG job ability Jump High jump and even Smite Surge. Thf JAS i dont think proc at all. We only focused on Melee and Light Melee Mobs no magic really.
