It was found out during Eureka and Hunts that this limit was being hit and players were left unable to land effects. For jobs like SMN this meant if you missed the window to get your DoTs in before the limit was hit, you were missing a large portion of your DPS. It is incredibly unlikely that regular content mobs will have this problem but still, jobs should be able to function in all content.
