If anything the AI might have a learning curve that will pick up on how you fight, although as I said I don't think it's 100% AI, but I could be wrong, I think I remember hearing it was you had still lot's of control over them such as who they attack and what skills they use. But the AI I think they eman is after they kill thier target then they move on to the next on thier own, or when suddenly attacked the spring into action or something long these lines. But like I said this is only speculation from me and what i think I remember hearing a bit ago.
