If you're into Destiny TTK and really want more from it, a group of friends and I feel that the coolest addition could be custom ship builds, custom weapon builds, armor infusions being cooler, bits and pieces from other items to create cooler items. Imagine having to farm for materials to put different pieces of a ship together. But you control how it looks and what parts from another ship are put into it. So, it's completely custom. This idea applies to all other aspects of the game, as well. It would be nice to have more customization then what's available.
