Grey item from Heroic Boss loot (Anzu, Auchindoun: Sethekk Halls)

[4thxHokage]

Is this grey item's drop normal? I don't recall ever seeing grey items drop from heroic bosses. I wouldn't want there to be a bug in the drop that could affect the Raven Lord mount's drop.
I don't know if this is the right section to report a possible error, let me know if there's a specific section or if I need to open a ticket.

Seeing that nobody answers, I would put it in the bug tracker; although the chances of this affecting the drop chances of the mount are low, I wouldn't want to risk it.
