I know people have done it flawlessly, but heres an idea i heard through some people to possible try. Would basically be a "perfect" raid. Meaning start to finish no deaths on hard, but along with that, not losing a single sync plate in the beginning, not letting a single vex sacrifice it's self to confluxes,, possibly not getting marked or missing oracles as well as not letting the templar teleport(not too sure on that part though) then going through gorgons undetected, then of course gate keepers/aethon, thats just my thoughts/what i've heard discussed among some i have played with.
