This is exactly how my fire team was doing it! It was crazy efficient, the only problem was there were SO MANY F*CKING BUGS. seriously, if it wasn't the sword dissapearing, it was the orgres taking 5 min to spawn, or crota standing up and immediately killing the sword bearer without his normal delay. We HAD him beat, we were on our last sword when it DISSAPEARED. Eventually some of us had to go to school/work so we couldn't finish him in time. Its just really frustrating when the dissapearig sword has been a known issue for a while now and there's still no fix.
