So I have only ever went through the Venthyr campaign on my demon hunter and reached renown 80. Now I have the Venthyr set unlocked for every armor type (cloth, leather, mail, plate). I went ahead and did Necrolord on my rogue thinking that same thing would apply. I reached level 80 and finished the campaign, but only the leather is unlocked. Am I missing something? why are the other armor types not unlocked yet?
