I'm one of the few healers that appreciates a berserk macro with a sound indicating 5 or so seconds until pacification. By macroing an oGCD ability, the WAR is sacrificing some DPS at the time of using Berserk with the thought that Pacification getting cleansed instantly will more than make up for that sacrifice. If I'm healing and I have a notification a few seconds prior to Pacification, then 99% of the time I can plan accordingly and fit an Esuna in.
