More of the exotics need to be bounties, doing the bounties is actually fun but some of the guns we get out of them are lame. Other exotics should be fixed to specific completions. Nightfall loot should exclude loot from the weekly and daily heroic and have exclusively legandary/exotic weapons and gear. Xur should exclusively be exotic armor weekly and do an exotic weapon a month (or twice a month) that way prices aren't inflated like most people who want stuff sold for 100 coins. And if he stays weekly then currency should be expanded to include vanguard/crucible marks, commendations, strange coins and notes. It would make the strikes useful again and people would actually have an incentive to not leave a strike so easily.
