Let's get a few things straight.
Scenario A:
If I log in at 1 PM and log out 10 PM, I have played the game for 9 hours. Let's say that of those 9 hours, 6 were spent crafting or leveling a class (something tangible and produces immediate reward for time given). Let's say for the other 3 hours, I decided to stand (idle) in a zone, waiting for a monster to appear, on the chance that I'm going to get claim to that monster. Let's go with a negative outcome this time. The monster did not appear. I log out for the night, with my effective time coming in at 6 hours of play (since 3 were wasted). That doesn't matter, though, because I'm hardcore and I decide that the amount of work I put in was 9 hours worth. (It's not, I just want to pretend it is because I don't want to think I've wasted my time. Which I did.) I do this for a week straight and for that week, I either do not see the mob spawn or do not get claim of the mob. I played 9 hours a day, coming out with a cumulative of 63 hours of play. However, 3 hours of each day were spent standing around waiting for a chance at something. So, out of 63 hours of play, 21 of those hours were wasted (time spent with no reward = a negative) because I received nothing from it. Whatever, I played 63 hours, I'm hardcore. (Only 42 hours of my time were actually effective, though.)
Scenario B:
If I log in at 1 PM and log out at 7 PM, I have played the game for 6 hours. Let's say that of those 6 hours, all were spent farming items and completing challenges for a tiered system involving Notorious Monsters. These Notorious Monster fights require coordination, the right combination of jobs, and a know-how to complete the fights within a certain amount of time. It is not content that the average player walks into and completes with their eyes closed. It takes me a week to make it to the last stage of the tiered system, where my Linkshell and I get to fight the HNM. There's no guessing about it. We passed all the stages and made it to the monster. The monster requires very specific tactics and we execute them like a well oiled machine. Although we've managed to kill the HNM, he doesn't drop anything but gil. At the end of the week, I've spent a cumulative 42 hours of time playing the game. Of those 42 hours, all of them are considered effective, because I received a reward (even though it was just gil) at the very end of it.
More TIME does not equal more EFFORT. More TIME does not mean being more HARDCORE. Scenario B is actually MORE hardcore than Scenario A, because Scenario A did not commit as many hours to END GAME content (and that's what we all assume when someone mentions hardcore). One person put in more work (the word "work" does not automatically mean effective work) than the other, but because the OTHER person worked SMARTER and not HARDER, they accomplished more within their limited time.
Fact: Time is money.
Fact: Windowed HNMs are like gambling. Gambling is specifically designed around something called negative expectancy. Negative expectancy roughly means that out of all the money I put into something, I can expect a ROUGHLY 90% return. No matter how I cut it, I lose. I did not get out of it what I put into it.
Fact: I'd rather spend my time being effective than wasting it. And I have a hell of a lot of time to spend as a disabled vet with nothing to do but play video games.
