I was paying VOG on normal with some randoms and a friend. I could not communicate with the fireteam. We were at Templar. His health was around 1/3 full. We were doing right strategy not worrying about oracles. I got marked and was shooting Templar. Suddenly everybody dies except me. It was weird but the relic went back to the starting position. I promptly ran to get it. Waited for the charge to cleanse, revived everyone, then proceeded to kill Templar. I felt pretty good about saving the team and finishing the check point.
