We successfully got a raid team together through the guided games, which I think is a cool idea and it operated quickly. However we reached Calus and 3 members needed to leave, we all voted to abandon for no penalty. We then successfully added 3 new members to the fire team while still in game. We tried one time and when trying to spawn back in one member couldn't spawn (fairly common glitch). We returned to orbit to get our member back, but when going back into the raid no checkpoints were saved and we need to complete the entire raid over again. We tried going back in through guided games and still no checkpoint was saved. None of the current fireteam members had a valid checkpoint. It's a little frustrating but I guess some things still need to be smoothed out. Be warned when using guided!!!! I plan on just using app or console to find people until there is a fix.
