There seems to be a bug in the Akil'zon module (or maybe Blizzard changed something).
During my last ZA raid I noticed that sometimes the Electrical Storm was casted before the bar in BigWigs was expired.
I also noticed that the engage_message is "%s Engaged - Storm in ~55sec!", but the first storm bar is started with a time of 50sec:
I think there is a bug in the german translation of Malacrass' soul_trigger.
As far as I can say it must be "^(%S+) (%S+) von Seele entziehen betroffen%.$" instead of "^(%S+) (%S+) ist von Seele entziehen betroffen%.$".
Compare to sacrifice_trigger from Terestian Illhoof: "^([^%s]+) ([^%s]+) von Opferung betroffen%.$".
