Confusion about what happened to my squad....Perhaps apologies are necessary on my part

So I played The Sunken Cell on GM 2 (which is really fun until you get to the Fury at the End.....That is IMPOSSIBLE to beat!)  with a few random people who were nice enough to join my makeshift squad.  We tried 5x to beat this SOB and could only get to about half health before we all got decimated.  Then I went to respawn to try again.....and I was alone.  I'm not sure what happened, maybe they all decided to give up as it was quite difficult on GM2 (I woldn't blame anyone if they did)....But nonetheless it was awkward.  Though perhaps apologies are in order on my part for setting the Difficulty to GM2 level instead of asking what most people would prefer.

I've been playing on GM1 and 2 whenever I play with a squad and it has been challenging, but also a ton of fun.  More so now at Level 30 than other difficulties.  And the Loot drops were pretty good....several MW Items, at least four or five.  But try as we might.....and we all gave it a good shot, we couldn't beat this mother flerkin.  Came close, but we beaten pretty badly in the end.   So to those who played The Sunken Cell with Rumble1138, please accept my apologies.   And if any of you would like to fly with me again, I would welcome you into my squad anytime.
