Hmmm... let's imagine a situation now. I know it may be a bit much for your low intelligence brain, but I'm sure you can do it. There are two people who got Gjallarhorn the same day. One who "earned" it, and one who bought it from xur. The one who "earned" it, got it from the deathsinger, which, counting the raid itself, takes about 20-30 minutes. Now, the one who bought it from xur has blown all his/her strange coins trying to get a ram from a helmet engram from xur, and has to run two weeklies. By themselves, they take about 30-45 minutes, depending on the team. After the second, they've spent about an hour doing weeklies, and are ready to buy it from xur. Tell me now, who's done more work?
