I've been thinking about the exotic class item and ways to improve upon it. Each class should be awarded 1 exotic class item upon completion of completing dual destiny. But the exotic traits should operate moreso like Armor mods. As you get a drop, you are awarded another one of the 8 options per column. There also should be a knockout system for the exotic traits. So that it would take at most 16 different class item drops to unlock all of the exotic traits in both columns. Because at this rate there are roughly 64 permutations per class. So just from a completionist standpoint that is over 200 different combinations for all 3 classes. And you would need to allocate 200 vault slots just for the class items.
