Yeah, i got that too. But i completed the path of the defender/striker and i believe the quest wont return to the abandoned ones. I know its just an emblem, the bullshit is they grant people emblems on the postmaster, for donating to Hati, vídeo of the month, beta players... Etc And saying they cant unlock it for someone who completed the quest makes no sense, they CAN. At least let people redo the quests, some are completionists.
