Nothing too fancy, but I think it would be rather cool to have a personal crib, similar to eso, to where you can collect and showcase some items around the house.
Raids, Strikes, Story Missions, Quest Missions, etc could all provide some sort of trophy you could display in your place. Prestige items will be diff from normal raid items as well. Could display armor, exotic weapons, etc.
Thoughts? What else would you like to see added to a guardians crib?
