We did it. Our first weekly nightfall was completed last night in 19:30 minutes. Then for fun we played some competitive crucible and then we did the nightfall strike. Again. Yes twice in one night we braved the nightfall gauntlet and won! Our second run was even faster at around 18:40 minutes.
The nightfall strike this week is in the Pyramidion with some Vex and Taken to fight. And lasers to dodge, and portals to warp through.
The loadouts mainly contained autorifles, though I had a scout rifle to snipe the hobgoblins and harpys which have a long range and deal massive damage. The new exotic rocket launcher was also a great help. I suspect fusion rifles and the line fusion rifle would help against the boss. In the first run we had two titans and a warlock. In the next run we had three titans. We used striker class for double grenades.
