I would agree with you Darksend that their needs to be an item for every slot on normal/heroic for 10 and 25. However I think they could do one better by making the items unique, as in not a replica with an extra socket and a hair more stats.
If they like the complete replica of normal carrying over to heroic I'm fine with that, but I would like to see some of the encounters change drastically (like they did in Ulduar) instead of be almost exactly the same with maybe 1 new ability added and more damage. Same goes for the loot. The current model as is makes heroic versions very uninteresting in my opinion.
There is something so appealing about backhanding someone across the face with a shield.
