Umm got to ask, how is this a hack? It is a bot to make levelling easier that is all. A hack insinuates that you are manipulating packets in order to gain an advantage in-game, or misuse the game in a manner it wasn't designed for. Bots are simulating human behaviour without the human aspect, so i believe this falls under the bot category and not hack.
However i do admit, for those too lazy to do the levelling themselves, good job. Also it should be able to work with any flyff, just add the ability to type in the name of the client exe it hooks onto.
