Achieves a good balance
They goal in the original change was to increase the difficulty of these battles and reduce the amount of time players needed to dedicate for the event. They believe that the new timer achieves a good balance, but Granado Espada vis does not rule out future reevaluations. They will be closely monitoring activity in the Abyss after the timer change is implemented to make sure that the battle rages on without any new negative side effects.
