the changes coming to Final Fantasy XIV after the first round of public testing, there are many older concepts going away, newer concepts coming in, and more than a few ideas that the community railed against which have been gutted long before release. The most recent issue of Dengeki has taken a look at some of the hard mechanics and numbers in the current test version, and that results in some interesting pieces of new information compared to what we already knew.
HP, MP, and TP, previously stats that could be raised as a character's physical level improved, now increase automatically with physical level. Three stats -- Agility, Charisma, and Luck -- have been yanked, with the six remaining stats (Strength, Vitality, Dexterity, Piety, Mind, and Intelligence) still raised via points. It also appears that damage will be applied to various parts of a monster's body, allowing for tricks such as disabling a monster's special attacks via careful targeting. While we don't know quite enough to start down the road toward min-maxing characters in Final Fantasy XIV, we're getting a clearer picture of the game's operation every day.
