About 3rd Party Softwares

[Nocte]

If files were altered. The launcher would not start the game. Therefore it reads the info from the database and gives approximate locations. Mmo's were and will always meant to have add-ons.

I believe this falls under 2.5 of the Terms of Service:
2.5 Data Mining. You may not intercept, mine or otherwise collect information from the Game using unauthorized third party software.

In other words, while some MMO's may approve of some, FFXIV approves of none, and hence really none that infringe the ToS in any manner should be used at all.
