And like I said before I understand that, however you can manipulate characters and mods to work around those mechanics. In this case it's only targeting one character because it's hard-coded into his kit to do so.
Don't get me wrong, I think he's a great introduction into the game, what I am saying is that this kind of hard countering/hard-coding is a joke.
It's really moving into dangerous territory with the way they program the AI to think. It's supposed to think for itself, make choice, right or wrong, not have defined directions that it takes.
