This really does need to be looked at. The awful drop rate is encouraging people who have little to gain from Southern Bozjan Front to sit around and wait for skirmishes like Murder Death Kill, Of Absent Friends, and Of Steel and Flame to spawn just for a miniscule chance for the notes to drop. There's little else to do that's worth it while you wait for them to spawn because mettle gains are abysmally low, and if you move too far away from where they spawn you risk missing out on getting to the skirmishes on time. It's a terribly unfun gameplay loop sitting around waiting. Being able to buy the notes with coins would be a welcome alternative, at least then it would encourage people to do other things while in the zone.
