So I'm assuming mostly everyone knows about using the fast travel nodes to finish the same public event two or more times. I'm also assuming everyone knows how it works, so my question is this: Do you have to stay as a fireteam the entire run after you join up after spark? Or can you leave the fireteam during the level grinding sections? If you have to stay together the entire time the run will be much longer than the solo version.

I might run them that's why I'm asking and I don't want to waste 4-5 hours on a run that won't get accepted.

Yes, you do have to be together after you complete the spark. Would hardly be a duo/fireteam run if you guys were solo a large majority of the run.

Ok, thanks for answering, I just wanted to clear it up and make sure.
