Many factions servers are highly dependent on farms and especially cactus farms. Having a program that at a push of a button would build any such farm I so choose would be game changing. Imagine coming back from school and you have a HUGE cactus farm making you money. All this would require is a accurate key logger and mouse recorder in sync with the server and having the correct items in your inventory. Ive tested many loggers and none seem to handle the complexity of minecraft i'm guessing this is because minecraft is 3D and the loggers are use to 2D Desktops.
