notice how they still say "armor sets"..... why use the word sets if armor is only 1 piece? i'm going to go ahead and believe for now that this is referring to the menu system and how its all organized in there... and like other people have stated.... why put so much work into the crafting system if there is only 1 armor type? ? why bring back enchanting if your going to limit its practicality so much?
it just doesn't make sense.... none of it.... i'm going to go take a nap and hope the answer if found by the time i wake up.
