My personal best on hard mode when one guy had a phone call and was at the start was 7 bubbles of super before the dead people were tired of waiting on the guy on the phone. All I did was punch the entire time. This was before HoW was even released. It was the most fun I had because someone else asked me to see if they would kill me before the guy got back. After popping 7 bubbles they all said that I wasn't going to die. So we moved on without the dude on the phone. That guy came back just as we killed Crota. He was excited because he finally got NLB from doing nothing.
