More to my point, recent Reddit quote from someone returning to the game after the current patch:
"Are zombies still omniscient with PhDs in Civil Engineering and Physics?"
Edited to add a few more quoted criticisms:
"It used to be a fun crafting/survival game with zombies. Now it's a scramble-to-survive run-and-shoot against corpse-like meth heads."
"In what universe can an uncoordinated, brainless, reanimated corpse hone in on an underground dwelling survivor and dig through stone to find them?"
"Hmmm.. we could go through the portcullis on a headfirst charge, oorrr we COULD run around to the back left corner, hit the rampart by the mountain, knock it over and do a triple back flip off the side to gain entrance on the roof. THEN we could GPS to exactly 0.234455/-1.340499 and dig through the roof! That will land us in the hallway where we can attack that pesky human from behind!"
^ Lol. I feel like I'm reading Tumblr memes, but it's about craziness of the upgraded zombie AI.
"I stopped playing as soon as zombies started digging. Zombies shouldn't be able to dig. And if I want to build an underground complex to avoid them I should be perfectly capable of that. Having the developer intentionally make them dig to counter player builds feels like the developer is intentionally playing the game against us by changing the rules."
And probably the most valid criticism:
"I've gotten the impression that the devs only added the ability to build because other games have it, but want to turn it into more of a run and shoot."
So... it's definitely not just me. And I wouldn't try to lock it down to 2% of the community either.
