Fireteam and I just did Dares of Eternity on LEGEND difficulty. Started with 4, as it says, then 1 person left after we placed the checkpoint banner. Another random person joined a minute later and after an hour and 9 minutes, we finished it on legend difficulty. No "Old Friends, Old Couch" emote. VERY frustrating. Is this because an original member left the fireteam? The Triumph states "2-4 firewall members" so we definitely should've received the emote. Any help at all would be great.
