The protection from the memories(bubble) seems to only work about 25% of the time. Unless we're missing something basic from the fight there is an emote/message to find safety in "Insert color" memory the entire group piles in and waits for the boss to finish the cast and the bubble then vanishes sometime your group is protected and sometimes it's an instant wipe. In normal mode this is ignored altogether but there definitely is a bug with it not working consistently in the expert version of the zone.
