Why aren't collectibles like arms packs, gold mask and Elder Scrolls Artifact in the outfit styles?
It would be handy to see what sets can be buy or what masks will be available for farming in the future.
Accordingly, those sets that you do not have they will be labeled as "not in the collection" but for that it will be possible to see them immediately in the game instead of going and looking for how they look like.
And that people would have fewer questions on the subject of "and where to get? And how to get" just in the description of the item to make a mark like the others that this set of weapons can only be obtained by buying at a certain time, with masks also the same, only that they can be obtained at a certain time.
This at least allows you to make plans for future outfits just by looking at what arms packs or gold mask you don't have and waiting for them to appear.
