Did you ever play World of Warcraft? It has far more in common with WoW than it does with FFXI (especially at endgame). The only things FFXIV has in common with FFXI are cosmetic, the races aren't even called the same things.
The two titles are nothing alike, at all. If you think FFXI is like FFXIV then you're saying FFXI is like WoW, Rift, Aion etc.
Endgame is dungeon crawling, crafing is easy and worthless, there is almost no community, there is no shouting for content you just click a button and are sent to a dungeon with people from other servers you will never see again. If you never played WoW then this is is like your eyes being opened to modern mmo titles, either that or it's the people that didn't like wow just because of the graphics.
I could never stick with any wow clone long term, they get incredibly repetitive due to endless dungeon grinding the same few instances and they have no soul or community. The things that make FFXI great do not exist in FFXIV and never will, it's as simple as that.
The reason FFXI and Everquest are still played in pretty high numbers is because they are unique and their will probably never be any more titles that play like them made ever again. They are something to be treasured because all that is made these days are constant wow clones.
