Devs, let me ask you this. How can you expect 5 people in a public queue fight off the Crystaline Entity with 2.5 million HPs, within 1 Hour?
So in order to do this event you need to barge in someone's Private Queue to fight it, and then only 1 group out of 5 will get the reward plus any of the bonus for doing the event.
Yeah, I think this event really needs to be revised.
