I understand the part with justiciar, where it should be less rare and not in the same table. Along with ghrazi rapier which shouldn't be in the same table since it devalued quite a lot past 2 months. We could probably add both of those to another table.
Although Sanguinesti staff, Ferocious gloves, Avernic hilt & Scythe of Vitur should still belong in the rarest table, if we put those in an easier table the price will devalue making them worthless items.
