Our developers are already addressing this Moonstone Set and the Scrolls issue, as you all know about recent changes. We cannot guarantee much regarding this situation, but we will forward a few good suggestions to add them to their planning to address this situation.
We also want to remind you that the Scrolls surplus problem only affects certain areas across the World Map since these do trade often. This means that the Scroll surplus is slowly going back to normal. This is because moonstone Sets age as players progress, inviting that player to replace it for something else.
While the "choose your Tier 2 Goods" is a fantastic idea, this will make players with several Moonstone Sets even more powerful. We also try to keep some balance among all our players.
