Call me naive but I actually trust him that those aren't macros, or at least most of them aren't.
Those aren't macros, everyone experienced in native two handed can perform the same lolfeint (including me), the reason people don't do it, it gives you a big advantage and it ruins all the fun of your opponent, lolfeinting is the second most gay thing in this game imo (first is fake peasants).However, countering lolfeint is much easier than you think, all lolfeinters are known players like Atze,Qoray etc..., when you come across them you will know when they will do that gay thing, and you can just spam them to death.
