You don't understand. It is humanly impossible to press the lillipa buttons in less than 0.1s and yet they do. And guess what? That's a 3rd party program at work. Just like how it is humanly impossible to get all 11 ticks of holding current in the first frame.
You say it's an unfair advantage, but it's also not easy to do at all. If anything, using macros in TAs is more unfair as it's extremely easy to just press a button do it and you need the program for it.
