Bring friends to the Loot Cave...or not

I heard about this loot cave while checking out Major Nelson's twitter. I decided to hit up the spot in the Cosmodrome and it didn't disappoint. There were about four of us shooting for drops for about I noticed the text "The Hive is moving against an enemy..." And then all hell broke loose. Elite Acolytes, Knights, Harrowed Knights, Elite Wizards start pouring on top of us. First a slow trickle and then it was a full on battle. We were higher levels, but when it's that many it doesn't matter. I'm a 22 Titan spec'd for Defender and boy did I make use of that Dawn of Light. I haven't fought a battle that intense in this game yet. It was an awesome battle that I'd love to try again sometime. Maybe if there were only two of us, things would have gone down differently. Maybe the programming responded to 3 or more players. Whatever it was, I can't wait to do it again.
