This week the answer is no, I used the under the steps tactic but I have successfully completed every nightfall strike without cheesing before atleast once but let's be honest when the loot drops are garbage why do the headache of actually attempting it legit. I know that I can do it and that's good enough for me. Also hiding under the stairs u are still able to single jump up and hit him with a rocket without taking a lot of damage then when he moves to the other side U come out of cover and hit him to force him back to the original side
