As others have hit on: 1) Major lack of content at this point. Our "endgame" doesn't really exist. We have 6 washed-up strikes (8 on PSN) with no difference between them in the loot you get, just aesthetics. And let's be honest: not challenging, no skill required. We also have 2 raids, the first of which was pretty cool, the second of which was not. That's it. 2) Destiny rewards casual players. After you do your weekly stuff, you're done till reset. 3 nightfalls, 3 heroics (only if you're hurting for coins), 3 gorgon CPs, 3 Atheon kills, 3 Deathsinger kills, 3 Crota kills. This will take you maybe 3 hours max for everything. After that, the rewards dramatically taper off, and there's no real reason to keep playing. You could grind strike playlists for a 1% exotic drop chance every 10 mins of playtime. 3) Xur. People know they don't even have to farm cuz Xur comes with additional free stuff each week, provided you can spend 30 or less minutes per week getting coins. You do your weekly stuff, spend a few hrs every week and you get everything Destiny has to offer in this current RNG system. No way to target specific drops. Maybe collect a few bounties here or there with telemetries to add an hour of playtime here or there, but that's it.
