Unfortunately not, I usually only do Dragonskin maps with FC/Linkshell and 3-4 people.

We try have everyone bring the same # of maps and random drop is kept by the person that gets it, and hope the RNGeezus evens out on the random drop over multiple maps. But the rolled loot goes to the map owner and honestly only Thav Silk is pricy now? Rush grass is like junk NPC mat and blue fox hide price dropping fast and even Thav leather is around 100k now.
