The zombies seem to be getting worse and worse, It should only take a few hits with a fire axe to kill a zombie and one to the head, also any swing of any melee weapon should knock the zombie to the ground rather than them standing there like a tonne of bricks(where are the ragdol physics they promised?)
What I want to see is MASSIVE hoards of SLOW WEAK zombies with much poorer eyesight, rather than 1 or 2 super strong usain bolt athlete zombies with binocular vision spotting you from over a mile away.

The zombies are indeed too fast, what we need is MASSIVE hoards of SLOW weak zombies! have a block in town totally riddled with them and you actually need to plan tactics to get around them or lure them out of the way, at the moment all we see is 2 - 3 extremely strong usain bolt athlete zombies with binocular vision that can see you from a mile away and chase you forever, its not fun. having to clean out hoards of weak zombies will be much more fun. Take this Arma 3 Dayz mod for example, Massive slow moving hoards (yes the video is all glitched out but it gives you the idea)

as in latest patch it does not take 1 hit with the fire axe but more 5-10, fire axe should always 1 hit to the head 2 to the body, every other melee weapon does stuff all, they just stand there like a tonne of bricks not even getting knocked to the ground, where is the ragdoll physics they promised us? what we need is MASSIVE hoards of SLOW weak zombies not 2-3 Zombies with super powers being super strong running like usain bolt with binocular vision seeing over a mile away. they are ZOMBIES remember! They are not fun to kill but boring as hell.
Take Arms 3 DAyz mod for example how it should be (even though they are glitching out it gives you an idea) http://youtu.be/Zm7a176IS8s?t=3m14s

It's unplayable and not fun. I know they are making it 'challenging' but if it's too challenging and too hard then no one will play it! simple! everyone will just switch to a day server like everyone already is. Night servers need to be fun. Take H1Z1 for example, that has amazing night time lighting, its dark but it's basically a full moon and the fog gets that awesome scary atmosphere. nobody wants to play night if all you can see is a black screen with a 1m diameter flashlight.
