Mechanically it is better, no one is saying otherwise, even redditors say that they enjoy combat vs humans more, it is everything else that is downgraded, like i said, you probably just don't care about this stuff to even notice it or being bothered by it, but the downgrade is pretty clear to my eyes because what is trivial for you, is not trivial for everyone.
Seeing zombies acting like stupid zombies, stumbling from roofs, stumbling on obstacles and not looking like stiff sack of potates was one of the best thing in the first game for many people.
