my Fireteam and I have been trying to get the Dust Palace Heroic strike for about 5 hours. We have tried doing strikes consecutively as well as leaving and searching again but to no avail. We are on the PS3 if anyone need to know that. Does anyone know why we simply cannot get the Dust Palace strike? Considering the fact that there are only 8 strikes on the heroic rotation I highly doubt that this is just coincidence.
