This looks that it might be the mod I have been looking for since I finished my first playthrough of skyrim. My main interest is not really combat, it's more RP and immersion so I was never interested in mods making enemies stronger or having more powers. But I've always been frustrated by the very low level of intelligence in all the adversaries we face.
Some mods like Duel, ASIS, Enemy AI Overhaul help some, enemies fight better as in have more finesse, the attacks parry will be better timed and they will heal, but still something is missing that you described perfectly in your video.
My personal experience with AI lack of "smartness" is this :
I play a sneack archer. I have of course downloaded enough mods so that my opponenents detect me in a more realistic manner (line of sight, light/shadow, type of armor, running/walking, activating a trap or making any kind of noise) and if I kill one of their team where at least one of them can see they will raise the alarm and not stop looking until they find me or an extremly long time has passed.
Seems fine, right ? Well there is still a major fault unfortunately :
They see one of them fall dead, if they are close enough they should even know it's from an arrow, they become alert, call all their allies close enough to hear their warning and ... run where the NPC has fallen placing themselves exactly where it's the most dangerous, in front of my arrows. Speccialy if it's a corridor, they will just come running and fall dead one after the other... it's depressing !
Worst even, if there is a trap between their position and the one they want to investigate they will activate it and die one after the other even if they see what happened to the x other before them.
What I would like to see is them approching to investigate much more carefully. Taking cover when they can, keeping their distance with the body, not coming all at the same time but maybe sending one or two scouts to check out where the enemy came from. And if someone comes close enough or was close enough to see it's an arrow that killed the npc then they should all take cover and look for the places an arrow could have come from.
And as for the traps, it's their dungeon, it's their trap they should know where it is and avoid it if possible, stay on hte other side of it otherwise or at the very least not fall into it if they see one of them die from it or if it's obvious like the swinging axes.
Your video with the dungeon was nice but it's, as many other mods more geared towards "non sneak" fighting tactics, nowhere to hide and all very bright there.
If you manage to do the same kind of thing with a stealth character, melee or ranged in mind then I will be more than glad to test it as much as you need and will gladly put in on my "must have permanently on my load order" list once it's finished
