Yeah, I agree. As a long time Warframe vet, the game has consistently changed locations that are primary farming locations for particular resources or drops. Ironically, though, with the sheer number of resources and drops. There are quite a few loot caves for individual objects, which helps vary the locations one might find themselves grinding away at for efficiencies sake.
I’ve got 2000 hours in Warframe spread across nearly a decade, most other games that I like clock in at about 100-200 hours, with most story focused games getting about 8-12. It really depends on routine updates and replayability
