I'm aware that this is not the right place for this post, and there is an active bug report going on, but I want to put a little more attention to this.
As of right now, BPC is impossible to pass on 25 man (not sure about 10 man).
The range of the individual shock vortexes is set to 70 yards it seems, meaning that everyone gets hit by around 35k damage when it happens, no matter your range to others.
As the raid gets hit by 3-4 vortexes during the encounter, we do not have the cooldowns to survive this.
The boss cannot be completed right now, and very urgently needs to be fixed, or we're going to be locked on 9/12 for the coming weeks.
