A random group invited my to do Crota for the first time, they had one guy that was giving specific directions and assignments to everyone. No one said a single word or was acting stupid. He gave the me the role of shooting the boomer knights and popping bubbles as often, another Warlock guy was like a popcorn orb machine infront of me. I was so focused on my job, that I did not see any of the action that other 4 were up to. Crota was dead in less than 10 minutes...
