LuckyBancho data shows that FF14 is in decline

There's also concern about the inherent bias in the achievement data since most players have their character achievements hidden.

I don't agree with that. Most people don't care about the achievement, why would they go hide them, they're visible by default. I'm sure the vast majority of player don't even know it's possible.

[edit]
Ok I'm wrong, it's private by default. Thus except being another hint in the direction there is some kind of fall, it's really hard to tell anything with that.
