Good things about new AI

Hi, I've noticed some interesting changes in enemy behavior that I like.
-Enemies no longer lock forever onto the first target they attack. They will switch targets to whoever is closest or whoever is attacking them. This makes the standard "scatter party and attack from range" tactic more challenging to execute.
-Enemies no longer stand completely still during combat. They gradually circle around their target, and may break off and change their target if they get close enough to, say, your spellcaster standing back there trying to cast a spell. This forces the player to be more tactically aware of position of spellcasters.
Anybody else noticing any AI improvements?

On the other hand, I'm used to playing with SCS, that could be why.
Had to change the difficulty to x2 damages waiting for SCS with BGEE because the fights were too easy.
Seems to me that, on the contrary, they haven't changed anything AI wise. Slightly improved pathfinding is probably all there is to it. Scripts maybe?
I've never been an SCS user, so the changes are probably much easier to notice for non-SCS users.
