Fine, I'll agree that Hunts dropping loot instead of currency would be a bad idea because of the good point you made but really, when I mentioned NMs, it didn't have to be exactly like FFXI at all. I know camping for them is boring, and that bots are a problem, that's why Hunts today have random spawning locations. It's just that the things you get from NMs sees relevance in difficult end game content. Here, the gear you can get from it serves as glamour. I never saw relevance in Hunts until the Relic which is just funny to me.

The idea I gave never even mentioned getting gear alone or even tomestones from it, but materials, and that you can use those materials to craft gear. I know Diadem is also farmed for because of materials. This is exactly the same thing. For the duration of the fight--that's why the fight is ranged to about minimum 20 minutes. Nobody wants to fight for half an hour, and 20 minutes is about as similar time you'll spend on raiding. People wouldn't really mind fights that take a bit longer as long as it's fun.

Besides, not much content in this game ages well at all, that's true. You'll know Midas will be irrelevant at the start of the next tier of Alexander. It happened with Gordias, Coil, and CT came back to life again briefly because of the Relic. End game dungeons are barely done other than for Duty Roulette, and they do a good job designing them, too. That's how themeparks work and they've wasted a lot of resources from it already.
