I've moved your thread to the #Feedback forum which is a better place for Destiny suggestions than #Help, which is more so for help of a technical nature with Bungie.net or Destiny. I'm not a Bungie Employee, but if it helps, I've seen DeeJ acknowledge the request to get more vault space in the past, it seems like a pretty common piece of feedback. All the same, thank you for sharing your thoughts about Destiny :)
