Probably the fact that shadowkeep gives no incentives for continued play. Grind this activity. Why? Because it gives you mods, and upgrade materials so you can continue to grind this activity, but it'll be easier. We got two armor sets, one for the moon, and one for the raid. So for most people who purchased shadowkeep, it's one armor set (which has such a [i]great[/i] design that I'm convinced the entire art department needs to be fired). We got a dungeon, with no specific loot outside of a reskinned ship (huzzah), and a bunch of retreaded content. I did most of it one or two times, and became bored, and so stopped doing them. I ran kingsfall, crota's end, Vault of Glass, and PoE multiple times in D1. Why? Because they had incentives for replaying them. Incredible guns (raids) with set stats so it wasn't a complete cluster -blam!- where you roll slide shot and icarus grip on a sniper rifle, because they had thoughtful perks. And the armor looked good too. PoE had the three exotics, and pretty good final encounter in the form of Skolas. They were fun, and provided loot incentives. But that's not on Bungie's list anymore. Unless said loot belongs to a certain pixie haired blue -blam!- who yells about her uncle far too much.
