I did a lot of stuff that was productive while lfp, I don't quite understand the commitment there. Besides that, your example is only 1 hour and 30 mins at most. Let us not forget that you also used examples like the dunes in previous posts, where most, if not all players, were LFP IN that zone, resulting in a time travel of like 2mins. Now, I do know players that exp'd for several hours. I've done it myself, and I would absolutely do it again, but trying to argue there is a time commitment in sitting there lfp? Come on lol. People like you are also people who complain about time commitment, yet are on FFXI all day. For example, you have several relics, a mythic, etc. I would assume you have spent more time than the issue you are trying to create, yet you argue that people don't have that kind of time in 2014? Even more, there is this implication that people who do want to supposedly play casual (even though they blatantly aren't) have to play on said server, when that is on the contrary.
I do get where you are going with though, would people really want this kind of stuff anymore with all the modern conveniences in modern day MMOs (for example, even though I love FFXI, I also do love dungeon finder tools). Well, like pointed out in the other thread exactly like this (and even this thread), we have provided several instances of where servers like this ultimately turned out more successful than where the game had progressed. That isn't to say there can't be both, but there is people who go crazy for this nostalgia crap and would LOVE to do it all over again. There is even people that some call "Power Gamers" who would love to play on a server like this just for the sake of getting to HNMs and preventing other people from ever killing one.
I'll even give another example of this crave for this nostalgia. There is a server for EQ called project1999 which trys to recreate the classic era of EQ. It has not only brought a population to the servers that hits numbers higher than servers hit in what some would consider the peak of EQ, but has brought new players to the server to experience something they never got to experience. Which has resulted in several people who fell in love with it and haven't left. So there is even opportunity to not just bring back old players, but new players in general.
Just to make it clear though, I do agree with you to an extent that a server like this will most likely not bring millions of subs, or even anything equivalent to what use to exist, merely based off what you said. This is more of a guilt trip for SE tbh, that we have hit a point in FFXI's life that this SHOULD happen, and there won't be any harm.
