Has the Dev Team considered implementing a system similar to one used for Empyrean feet armor? That is, trade three unwanted items for the one you want.
I understand that to preserve the longevity of content, this type of adjustment is usually something that would be applied to older events; but Adoulin content seems to be cycling through a lot faster and rapidly becomes less accessible. On my server, there is little consistency Colonization Reives, and more often than not, no one is fighting them. I suspect many gave up before even receiving their JSE capes due to the tedium. An exchange system would be an attractive option to those players.
I'm fortunate enough to have in-game friends with the right jobs and play time that allow me to clear reives without depending on the general population, but I suspect I'm in the minority.
