Thinking up of an idea for Xur moving forwards with Forsaken. Exotic rerolls. Currency used can be determined but being able to rerolls a perk on exotic armour would be a good shout. At the moment, you not only have to drop an exotic but also be lucky enough for it to be the one you want. Then, you have to be further lucky enough to get the perk you want. If you don't, the new exotic drop weighting means you're less likely to get that armour piece again until you have the other exotics. So, rerolling, even if time gated would be awesome.
