Some of our observations for this fight...
Apply construct skills to boss. Win.
Have constructs up from where your raid was basically 1 tank and 6 constructs alive at the time of kill. Tank dies, leaving some non-plussed constructs standing around the corpse. Aggro them while taking a photo... die because at least 2 of them have 30+ million health. Watch the boss despawn, taking his purples with him. Submit ticket. Facepalm.
On a more serious note, we began by 3 healing this due to excessive numbers of explosions on phase 2 causing many wipes. Once folks got the constructs figured out however, the fight was greatly simplified by dropping to 2 heals, since most of hte damage is avoidable and the extra DPs means constructs get to <20% faster, and Living Ambers die faster, providing everyone a larger comfort barrier.
