I used this tool for a couple of days and then it occurred to me that seeing how this tool hooks some in-game functions that it probably violates SE's TOS. So I re-read (okay, lying, first time read) the SE-TOS, and FFXIV-APP definitely violates SE's TOS, making the use of this program banable. While I doubt SE would a) know about you using it and b) care, it is still potentially banable, and I really think that should be noted somewhere on the FFXIV-APP.com website.
The following activities are also prohibited in FINAL FANTASY XIV.
