There is no and I mean no reason to do it. There really is no reward. I don't desire any of the exotics from this DLC in terms of weapons and I have every good elemental primary. Again the items they came up in terms of weapons and such for this DLC are useless throw away items I would bet on purpose to get us ready to throw everything away for the next in which they make us basically start over on weapons. I don't know this but I fear it is the plan.
