Kaivax:
The change we made was to make the item no longer throwable. This was done to fix an exploit where players were throwing the item to transfer wealth across realms. It can be quite valuable. We decided that Haunted Memento was old enough and valuable enough that preventing it from being thrown was a reasonable compromise.
(still searching for patch deets about the change to the shade)

6.0.3
It was the #1 source of creature spawns within the game, which was causing server performance degradation, and during launch we changed its behavior as one of many tweaks to help recoup some server headroom. Due to the ongoing demand on the game service (and likelihood of similar demands in future expansion launches) we’re not currently planning to revert it to its old behavior.
