As for FF14 the data is not obfuscated at all. Of course they are not at a fixed position (but they are not in any modern game, and even if they were, this would change at each patch), but the data pattern is easily found when scanning the right portion of the memory, and it takes a matter of seconds (you can even scan the whole memory if you have doubts, works pretty well). The data structure is extensively documented in some forums.

But even without documentation, it's only a matter of finding the structure once. I have already done this for few games (not for FF14 though), and believe me, with the right tools (and some understanding on how memory works), if nothing is obfuscated, it's only a matter of time.

For the average bot developer, FF14 is plain boring.
