The fire team you are trying to join can't be joined because the activity they are playing is about to end. Try again soon! More like bungie, try again. No SAVE POINTS IN THE ARENA AT ALL! If you make it to round 5, and get error coded, it will not let you rejoin! What were you thinking? Error codes are a daily burden for any longtime destiny gamer, and you didn't anticipate this scenario? Idiots! I hung in after all the bull with the updates, failed raids, and glitches. Even ignored the glaring difference between what was promised prerelease, and what was delivered. But this is plain ignorance towards the consumer. I hope you fix this issue, cause PoE was a fun twist. But until then, I cannot handle the disappointment. Idiots.
