As the title implies, is this quest supposed to be account unique or playable with all 3 characters? The reason I ask is the stupid reward system allowed me to accidentally select the catalyst which I already had... and I'm pretty much wondering if I f'd up my chance of getting either exotic I didn't have via this quest or am I going to have to grind it out via the dungeons? It's stupid it allowed me to even get a catalyst I already had. Literally every other catalyst from Xur or elsewhere doesn't, so why this one does... who knows?
