so ive gone throught a couple of raid dungeons, (most notably AQ and Naxx) and ive noticed you can aquire the items needed for their respective sets, but the quests to create the sets are missing. Am I doing something wrong or is the quest just missing? and if so could they be fixed? or perhaps a vendor to trade the items like t4 and t5?

Thanks
