Yeah, I have noticed that thralls are not so snappy since the update. I will send them in to attack a group of enemies, and once they have killed one enemy, they will return to my side instead of attacking the other ones. Like you said, that’s not very aggressive at all. They will also seem surprised when the enemies go to where they are an attack, standing motionless for a few moments before drawing their weapons and attacking back. Previously, they would continue to attack a group of enemies and would only return to me when they were dead.
