I think I just saw this in action (monster dodge):
I entered Phobos level 3 and there was a group of formers nearby. I began shooting them with my pistol (AoMr) and one of the bullets hit a different former than the others. It happened before the formers could even move, so it definitely wasn't dodging.
It was in graphic version. If I didn't read this thread, I'd think that I just imagined it, but I'm pretty sure it happened.
BTW, I'm playing keyboard only. I just realized that it could be explained by me bumping into mouse, thus changing the aim, but the next bullet went back where I was originally aiming,so that sounds unlikely.
