If someone is to blame, it's Producer Naoki Yoshida, who admits that "the sheer volume" of his suggestions prompted the delay. But it will be worth it, he promises.
In a new producer's letter, Yoshida hypes the patch and in particular its changes to magic casting. These changes will be "almost identical" to what the game will see when it hits 2.0. He's extremely excited to announce that adjustments to alchemy and culinary professions -- the medicines and food, specifically -- are almost complete. Finally, he reports that the team is deep into testing the two new instanced raids that are coming with the patch.
Yoshida also thanked the community for its feedback over the upcoming server merges.
