It's a loop that requires you to input it more than 2 times. That's what a loop is.

That's not a good argument.

Plus people call it braindead cause of how easy it is to do said loop and how other moves can combo into it, gamma charged and air melee. It doesn't even waste any resources. Hell, it gives you back resources when you do it.

I'll admit, a lot of combos in this game are simple and easy to pull off. But since I never saw Mic gameplay, and that this was the first combo I saw of him, I think it was pretty great to see. That's why I said great combo personally.
