Obviously there are no stat info on it and I have seen people freaking out about it. Heres the thing. It may be a LVL 1 helm with stats you will out level in 8-10 levels, which if this is the case, who cares.
It may be like the Leoric's Signet, and be something you would use while leveling Paragon becuase of the Bonus XP.
It may be like the Hellfire Ring, LV 60, potentially good stats and bonus XP.
We just don't know. However my feeling is this. If they add it in game, should PC get it too, make it a new LEG drop in game, or heck make it a LV 60 Craftable like the Hellfire ring. Something else to farm for?
Adding an Item in a version of the game where Item hunting IS the game to me just seems like a real jacked up move for Blizz to pull...
