Alright, it seems a lot of you can't comprehend some pretty basic English, so I'll explain. At this time until the 15th, you don't get the emblem from the subclass quests. And anyone who completed beforehand, won't be getting it when TTK drops. This is what "retroactively" means here. Edit: I'd also like to mention that all hope is not lost. Bungie has been shown to be easily able to track player progress, and they can send off emblems to their rightful owners themselves manually. Maybe.
