Something I've heard from several of my friends who play (and something I've experienced myself) was confusion about having to manually put the Reaper's Mark up in order to complete the run. To avoid the confusion with newer players who are just trying the voyages for the first time, my suggestion would either be to have the voyage equip the flag automatically when it is active, or (more simply) just have a disclaimer when you buy the voyage from Duke, to the effect of "WARNING: completion of the Reaper's Black Powder Run of the East/West will only count towards commendations if the Reaper's Mark is equipped manually before embarking on the voyage."
It's not a big change, more just QOL, but I think it would help a lot if some kind of message were added before the Black Powder voyages rotate out, just to stop people trying to get the commendation wasting doubloons accidentally, or just not understanding the prerequisites of the voyage, especially with new players who might want to try it but don't quite know what the Reaper's Mark is.
