Been a LONG time, but I remember that I had a couple of "owned by no one" talisman for crafting given to me as gifts, not long after ML was launched. The way they worked, is they became blessed for the first person to equip them, and thus changed to "owned by <player_name>". Anyone could use them after that but they would only be blessed for the "owner". Well, we fussed about that being on Siege, so they corrected it.
The properties on my talisman didn't go away from what I can recall, just the blessing part when they made the change. I thought they made the change across the board for any existing "owned by no one" so that if equipped, no blessing would be attached, but given the track record in this area it wouldn't surprise me at all if the existing ones which had never actually been equipped by someone, and thus had "ownership" established, remained intact. *sighs*
*edit*
Finally found a developer reference to
this issue mentioned by a player, and the actual
dev post.
That was also the big publish where we got our Siege Bless.
