According to Cozmo on Reddit
[quote]The quote you are referencing is referring to "Faction Quests" not "Subclass quests." The subclass quest is working as expected and grants a class item. The class emblem you seek is a reward for a different quest that will be available on 9/15. Sorry for the confusion, please pardon our dust during this transition week.[/quote]

SO we're not getting them from the Class Item quests, and they're an entirely different class.
