You've got to realize too, Yoshi and team were, from a development standpoint, handed a steaming pile of goobue dung that was 1.0. It was a disaster and you can't completely remake an MMO in just a year or two. So they had to build upon that structure. They could have easily thrown their hands in the air and said "hell with this" and watch the final fantasy brand go down in flames like Dalamud - but they didn't.
Because you went through the original story, you got to experience something these new players (or those who use a potion) won't experience like you did. And that's okay. Because it's a different time, a different scenario and different play styles. Its like people that grew up in the 70s and 80s talk about how different the world was back then compared to kids growing up now. Today's kids would marvel at the clunky and expensive "technology" of yesteryear, but I wouldn't want to inflict it on them because that's not how things work today.
