I do think that to some extent it's somewhat pointless for people to be trying to figure out formulas for algorithms that are likely still being tweaked and adjusted and may possibly undergo further revisions.

However, I think that with the addition of the materia system, where a significant amount of stat customization gets placed into the player's hands, SE is somewhat obligated to give us more information in the future as to what each stat does and why we would prefer one stat over another in a given situation.

High level materia is a large investment for a player, if the game is going to provide separate materia for say STR and ATK, then it's forcing the player to decide which will be better. If the player's goal is to increase their damage then they should at least have a small sense of how these variables will affect their damage differently so that they can make a correct choice.

SE can let the hardcores figure out the exact formulas and algorithms for themselves, but I think they owe it the general population to give them a general sense of how these stats differ from one another so that they have a guideline for making sound decisions and not have to waste time and resources making blind assumptions that may not be optimal for them.
