So, according to wowhead, and atlasloot and ect, Heroics drop Heroic versions of the BOE gear.
An example
Temple Band from HoO
w ww.wowhead.com/item=56111 <- non heroic
w ww.wowhead.com/item=56439 <- heroic
(Sorry, unable to post links)
And yet, all I have seen drop is the non heroic version and this is out of both normal and heroic runs.
Is this a mistake on Blizzards side, or just the databases?
