I'm done! Got it this morning... Finally got that sweet title!
I advise that these items no longer appear after a restart. Got 3 restarts these days, tried doing a full circuit after each reset, and didn't find a single one of them.
However, I believe Blizzard may have changed the respawn rate as well. I was finding the relics with some frequency, even got into a looting spree of 8 in a row =O. I may have just gotten lucky, but it may very well be that the respawn rate is a bit more friendly.
EDIT: Also, I didn't use Cross Realm, and got all of them on a single toon. Was planning on using both, but didn't have to!
