A bit biased poll. Could have just asked if people find it useful or not.
Anyway, like any extra addon tool it can be over used, and I have done a few macros where in action I realized that it was easier to do it myself than have a command, and I was using VA because I could, not that it helped. But I've found it a great extra hand for a number of things, especially those that require a macro, where it was faster and allowed me to focus on other things.
Could I play ED without it, sure. But I enjoy using VA as an extension, and it frees up buttons for things that I'd rather control directly. And no, I don't feel silly talking to my computer, I think it adds to the feeling of the futuristic setting.
Whatever works for each player.
