From what I've seen on another post about what people got this Nightfall and my own experience, yes. I have done dust palace countless times and haven't been able to get any of the cloaks or Treads upon stars. Do the Nightfall version and I pull Treads on my Hunter and the Flayer cloak on my Titan. My brother also pulled his first Treads on that second run. So it certainly seems that way unless it's all just a big coincidence.
