I too was expecting more when it came to ICC, and it does feel unfinished (Like the rune portal looking things outside every wing). I was hoping to bust into prof patricides room and see him working along with other chemists (Kinda like BWL) and the such.
Also it doesnt "Feel" like your progressing up the tower to the lich king, When I think of the frozen throne this is what I thought I would have been climbing on the final path to the lich king
