This should be separated from the rest of the armor the same way the eradicator mask is. The eradicator mask came out after the armor, so it is properly done that it is not required for the collection of the armor. The Revan mask was in one pack, the sash and gloves in another, so should be separate collection purchases. If anything, require the chest and leggins since they were out same time as rest of the pack, but not the belt and gloves. Bioware should really address this knowing the mask is one of the most beloved items in KOTOR universe.
