i logged in yday and broke down everything too and ended up with 18k bright dust. no idea what its used for anymore but thats cool. if you go to rahuul, the engram dude, he'll convert 5x at a time shaders instead of 1x (why isn't there a 50x option too lol).
you can "retrieve" exotic weapons from a kiosk somewhere, right? like reconstruct it once you obtained it once? i didn't break down any of my exotics, just wanted to check first thats true. i doubt i'd ever reuse any of em again but some of them i remember being very cool.
i never played forsaken so its nice being able to play some of the stuff and see what i missed, but i gotta finish stripping my characters down. I also have stadia on pre order (god knows why) but that'll come with 3 free months of full Destiny 2 so i figure that'll be a good way to test out stadia and d2 at the same time.
