Why not make it so you can pay Legendary marks for emotes or Eververse packages? I would definitely pay 200 marks for a single emote as opposed to spending real money. However, I doubt Bungie will take any consideration into this. It would be a really nice and welcome feature, not everyone can fork out real money for "Silver".
