As everyone knows you get 1 dark run a day at 100%
But you could help team mates if you could get a second at 50%
Or if you didn't get desired arts in first you have a chance in second to get a reduced rate but not a normal red star run
This would bring back trading as well

Or allow 3 planets worth of DRS boosted arts, spread across however many DRS runs it takes to get your arts. Only arts brought out of the star count. Then we're not wasting bonus runs to help teammates. Also, if you only bring back the arts you want, you could potentially run multiple DRS,being selective about the arts you bring back so you can research what you want.

You could just coordinate with your teammates and do it all together...
