Just get a Red Onion Helm if you have a tank. I would prefer for these items to stay rare as they were rare for very good reasons. For those who bought the trash fire of Final Fantasy XIII, Asuran Armlets were like a silver lining. Very similar for the Onion Helm from the 1.0 Collector's Edition. The boots were also a thank you gift for playing XI and XIV at the same time, which meant those people were dedicated enough and it was SE's way of saying "thank you" for paying for two subscriptions at once.

There are certain times when I like more glamour items to be available for all, but this is not one of those times. Some things should stay rare.
