Don't Warfront Me

seems some of the items are not properly triggering the appearances / set /achievement. I just got the Honorbound Vanguard's leggings from warfront and it didn't complete my set or award me achievement

Super broken achievement. There seems to be three separate appearance sets that drop from Warfronts (or at least I think they all drop from Warfronts). But as for which pieces from which set count towards the achievement seems pretty willy nilly. I talked to a GM who said that you have to get the exactly correct pieces for the achievement, which is... dumb. Let's call it what it is.

Any items that you receive from the weekly quest Warfront: The Battle for Stromgarde or Warfront: The Battle for Stromgarde do NOT count towards this set. Nor do the items that you actually receive from winning a warfront. You can only complete this transmog set by getting pieces of gear off of the rare mobs out in Arathi, doing World Quests in Arathi, and Emissaries. Actual Arathi Warfront Scenario AND Weekly Quests do NOT count towards this set appearance even though the items have the same name.
