Are you saying that you need a macro to type 1 inc snow to keep up with premades? Cause you are either going to see the guy coming, or he is stealthed and you're about to be CC'd for at least 2 seconds to type.
No, he didn't say macros would solve the issue. He suggested that VOIP fails the test set forth by Phillip:
...Think of it as an evaluation on if you are using a tool that gives you an unfair advantage over somebody not using that same tool
Voice comms are a tool external to the game
that enable faster responses - that's why they're used, right? If anything, I think he's written a verbose feature request (add voice comms to the game itself).
