Some new players in my FC asked me to come tank Brayflox story mode, cos their tank dropped out. I'm new-ish too, so I wasn't sure if I did this right, but I opened duty finder, and clicked party in progress for Bray. I ended up with a different party, not my FC mates. What's the proper protocol in that situation? Is it acceptable to leave the party and try again to get matched with the right group, and if so, how do I do that? This time I just stayed with the party because my FC mates got a tank a minute later. But I need to know for next time.
