Passenger missions are generally good for Grade 5 rewards. I just don't often have the patience for them

Back in the day, I used to do a lot of Passenger missions. Then, you could make a lot just by stacking transports from Point A to Point B. Now, it seems the large payouts are mainly for sightseeing and the Rich Tourist A to B are less lucrative. If there is a decent Grade 5 Material reward, though, it is worthwhile.

For whatever reason, it always seems Biotech Conductors give the BEST trade ratio at the materials broker, so I usually do take them when offered as a mission reward even at the cost of some credits.
