I think Ai also respond accordingly to the amount of enemies they face i.e the ratio of them vs enemies, but also supression fire, so with the increased range and devastation of weaponary, in my experience the Ai in this mod behave less like the blob masses from previous vanilla versions. I've never been particularly unimpressed with the Ai unless I'm playing a test map with no cover and just an open space in which case the Ai either go forward as a mass or retreat as a mass.
