​It will be easier for both developers and players. Why not change the helmet customization system? It would be much easier and more convenient to allow changing just the basic version of the helmet, and then in a separate menu select decoration for this helmet, skull, hood, laurels, etc. And there will be no problems with heraldry on helmets, just release a helmet decoration in the form of, say, a drop of blood, which can be attached to each helmet. Done, you have several helmets at once for the Blood Angels cosmetic pack. I think the idea is clear.
