There's a lot of companies out there that keep claiming that their bugs will be fixed in a timely manner, yet most of them haven't fixed them six months or a year on. What isn't explained here is that Square Enix doesn't see a lot of their choices for gameplay as 'errors', 'bugs' or even 'problems'. Some parts of the game are severely hated because they either make no sense or there's something convenient that's missing that most MMOs have done in spades lately.
You can only fix so much before you get right down to the very fundamental building blocks of the game and realize that when they say they'll fix things? That DOES NOT mean that what pissed people off will be gone, fixed or changed in the least. Bugs and such are normal, they get squished. Finding, say, the crafting system is a clunky pile of crap? Chances are it'll stay that way for a good, long time until people get pissed enough to dent their bottom line.
