Editado por LeadEatter153: 9/16/2019 7:38:21 PMI managed to get Rat King's catalyst Saturday night doing the normal Heroic, so they do still exist. If I were you I'd just pop a fireteam medallion and go in not expecting anything but tokens. If you still have pinnacle weapons for the Vanguard or Cruicible, focus on those or any other specific loot you're also looking for. I got 2 catalysts while grinding for those and got Rat King when I was doing my Ikora Tribute.
I just got the prospector one a few days ago when i was trying to complete one of the eververse bounties.
