I dunno. I've played various MMOs, put the most time(7 years) into FFXI, and the second-most(2 years) into Aion and I never really cared about "WoW clones" or such. FFXI was terrible for a new player, especially in the later years, unless you had friends that could hook you up.
Most people are just blinded by nostalgia, looking back on the "good ol days" and not remembering the 16-hour spans of nobody but you and the random DRG/MNK or THF/RDM LFP. Some of my best times were had in Vana'Diel, but it's time for a new experience, copy-pasting from it would not serve the purpose people think it would. Are there some things I'd like to see? I suppose. But I honestly think I'll be fine with 2.0 at least. Either way it'll probably be the last MMO I play. Don't have the time like I used to for enjoying MMOs.
