Crowd control

While Playing more of the game, one improvement that really stands out is the guard AI. In the last game you could kill 50 people and then just hide fro 30 seconds and no one would be after you, despite still walking around in a big imposing hood. Now if you have a wanted level all guards gradually become aware of you as you walk by (shown by a little marker) and if you don't get out of their sight quickly they will recognize you and raise the alarm, running around or climbing walls helps them recognize you even faster. To counter this you can now blend into crowds, hire prostitutes/thieves/mercenaries to act as cover/defense, or the old standard of hiding on a bench or a pile of hay (but that dosen't work 100% of the time).
