The Ar-moire is very disappointing. You can use it only for certain special items.

I just got my relic for my White Mage. I'd like to be able to put my ilvl 70 crafted HQ staff Alkalurops in the Ar-moire not my retainer. Yeah, I'm going to only be using the relic from now on but Alkalurops is a nice weapon and I just cant bear to throw it out.

Also, why does the Ar-moire reset spiritbond to zero? It's not like you can sell or trade unique items if they have 0% spiritbond anyways.
