As much I enjoy TES games and being a huge fan, skyrim so far got the most awful AI that I've came across. I consider myself casual gamer, I got plenty of games around. But Skyrim really comes at top of having most pathetic AI ever.
There have been reasons why I always played melee character at this game and for sole reason that AI is crap. So recently I tried out to build some kind of a death knight style character.
I went two hander for same reason I mentioned before, to skip this stupid AI so I can at least defend myself properly when AI starts malfunctioning. But fun did not last long, it drove me insane in fact. Every time you revive corpse it just stands there like complete imbecile doing pretty much nothing, then it runs back to pick up a weapon and after that runs back to Enemy trying to swing at it and usually misses.
I'm at the point where I want to give up because current experience of playing a summoner type character is just [censored] awful. I'm not sure if any one else has same experience around these forums, but from what I understand and from what I read around google is that every one is at same point.
Not to mention follower characters being completly and utterly useless, they usually move like idiots. Farkas comes to mind.
