Alright,i spent literally all day trying to do this, I looked at so many videos and comments on forums and nothing was working. This is the way I did it with nearly 2 minutes to spare. First,do not attempt to do this with more than 1 hunter,you are going to have a much harder time clearing adds. Have 1 night stalker and either 2 storm callers, 2 sun breakers or 1 of each. When you get into the room,immediately focus on the blights. The sunbreaker and storm caller pop supers and annihilate the adds,this should be extremely fast. Titans,you should be running the perk that gives you health for for every kill you get,this makes it very unlikely that you'll die. After the rooms cleared by the supers,night stalker shadow shots the boss and everyone rails on him,shotguns and swords are what I used and I highly recommend using the exotic sword if you have it. The next wave of blights spawns and you rinse and repeat,if you don't have your supers quite yet just focus on the blights and pop some adds until they are back,this is most important for the two dpsing the adds, so, if you can, use anything that fills your super quicker. Once the Warlock and titan have their supers, pop em, rinse and repeat. The adds should be pretty easy to handle this way. As I said, I personally would just use a sword when it's time to hit the boss,especially the exotic. While tethered the swords combo does around 10k and,so each combo collectively is over 30k dmg,this should make very quick work of the boss and even if it doesn't leave you with as much time as it did me, should be very effective. Hopefully this technique helps some of you and if so pass it along to your friends so they can pick up the sniper before it's too late! Edit: yes I know it's possible other ways,yes I know there are people Who have done it with all 3 hunters,these comments are predictable and pointless. Really no need to comment on how you did it with 3 hunters,congrats to you but I'm showing the way I did it with ease.
