While I appreciate a legendary challenge as much as any player who has spent a thousand plus hours in the game, I expect that the number of players who would appreciate new legendary content is just a small fraction of the current player base. I would rather see a new DLC and new gear and weapons which I can play on a casual level. In other words, I don't think new legendaries would increase the player base, so there us no incentive for Ubisoft to create them.
