This "classification" already exists and the game itself made it, from "extreme" to "novice" :


 * Dokkan Events / Prime Battle (Extreme)
 * Special Events (Professional)
 * Super Strike Events (Professional)
 * Story Events (Advanced)
 * Strike Events (Intermediate)
 * Bonus and Flash Events (novice)
