If enemies look dumb to you, not reacting to something which happens at the end of the road or simply standing there waiting to get butchered, it's not because their A.I. is lacking... sometimes... but because you are overpowered.

And I don't mean that you have a supertech suit and they don't, I mean that you can use 3 kinds of stealth while they cannot: meaning you can at the same time turn invisible, use natural mimetism and you have magical equipment which can't be seen nor heard in long distances.

After you give enemies some working eyes and ears as well as legs, they become scary foes. They move in packs of 10+ people, which can be extremely tough to deal with even with the most cheap invisibility shots tactics, swarming every place fast as they do.
