Says that it requires "Riding the Storm" quest but I don't have that in anywhere in my collected quests or in the quest archive. I've visited Ikora in the tower like it instructs but she doesn't give the quest either. I really want to use my titan more, but I can't really get full use out of it without all of the subclasses unlocked. I have a lot of other work put into my titan and don't want to have to remake the character again to fix this either. Is there anything I'm missing to try fixing this?
