No, I had me and 3 others, as stated in the original post.

I can see your game you had 5 players.

So a dude leaves after 10min, no warning or communication and that kills it for everyone else? Well that sucks.

The Triumph clear states 2-4 players, not 5. [quote]Complete Dares of Eternity on Legend difficulty with a fireteam of 2 to 4 Guardians.[/quote]

Yep, and at no stage was there more than 4. It does not clearly state anything about the group changing. 1 PoS leaves when everything is going fine and was replaced. never more than 4, as what the Triumph states. If it was 'clear', then it would say 'the same 2 to 4 Guardians'. I am very annoyed. I stuck it out with 2 rather new guardians despite the wipes and then not to get because of an unstated rule is extremely frustrating.

At the end of the day you now know what needs to be done to get it done and the activity doesn’t take super long to complete.
