Oxygen is forgettable. It barely has a gameplay impact and seems to only exist to support the space theme.

But the grinder, I miss when I play 2 or 3. It gave me a reason to look at loot more closely and collect more, even if it was low rarity or irrelevant to my build. I liked having a more controllable way to get new weapons as an alternative to relying on drops and vendors. It’s also a good sink for moonstones.

In a game about loot, making you care about loot is pretty important. In the other games, there’s pretty much no reason to care about white and green drops, so why even drop them?
