This might have been patched March 27, 2023.

Allows you to maximize group Major Berserk uptimes when boss humping by preventing the use of Atro Synergy when you have Major Berserk active. Takes advantage of a change in U37 allowing Atro Synergy to be picked up by multiple people, thus allowing the Major Berserk buff to last longer if the synergy is spread out between group members.
