Okay, it seems that the Guardian Abilities card can now be unlocked as I have seen many people with it on Destiny Tracker. I am talking about the card in the first section under Subclass. However, for some reason, no one will tell me how to unlock this card. I personally believe you have to make a new character of each class. I need to finish my Hunter Grimoire card before I can delete him to test this myself. If anyone has an empty character slot, can you please test this for me? Just make a new character, launch the first level, then delete the character and make another of a different class. I have one of each class already made but still can't get the card to unlock, so even if you already have a Warlock, make a new one anyway then delete it after you launch the first level. Finally, if you do manage to get the card, you won't get a notification. You need to manually check on bungie or the App to see if it worked (the House of Wolves card can also be unlocked now by going to the Reef for the first time after the Stranger's Call mission but you won't get a notification for that one either - you don't need a new character for this one, just join someone else's group before the go to the Reef). You're assistance is appreciated! Merry Christmas!
