I don't mind a bit of mistery every now and then, I think I actually like it. But FFXI took it waaaaay to far for waaaay too long.
Either they start giving cleared info on an average base (which they seem to be willing to do) or they leave the mystery for a bit (weeks? months?) then they make an official post to clear things up about complicated mechanics.
I don't mind either approach, or even both at the same time.
But leaving things as they've been for the past 11 years is wrong imho, and the more time goes by the more wrong and anachronistic it seems to me.
