20/20, just got a few mins ago.
There were 7 available @ 19/20, ended up looting the Virmin chest.
Still 6 I do not have, so guess I'll collect them as and when.
Since 5.1, and the items not just spawning at server restart, it's been much more viable doing a circuit every couple of hours or so.
Have not used any x-realm grouping to get any of the rares.
