The best years of my MMO life was in 2004. FFXI couldn't be touched compared to any other MMO.
The fear of dying so you wouldn't lose XP and down-level. Nothing topped the sound of down-leveling when you heard a person from another party next to yours die and lost his armor because he dropped a level.
I remember when mobs would chase you all the way to end zone and would turn around and slaughter other parties until it was killed instead of vanishing like it does now.
I stopped playing when they introduced Level-sync. Personally, that killed it for me.
I just wish FFXIV had SOME of the mechanics that made FFXI so successful.
When FFXIV fixes the party-based system and makes it more like FFXI is when I'll take this game seriously. And throw in an AH too. That wouldn't hurt either.
For now, all I can do is wait.
