Zombies are one of the most useless mobs I have encountered in any survival game.
What should be done is an improved AI for Bears and Wolves. Make them some dangerous sons-a-bitches, and you'll have an actual competent enemy. I also think their should be an AI which stalks and hunts players, sorta like a mountain lion. If you have a wooden door, they'll start clawing at it, and ripping it apart, and possibly break it down in five to ten hits.
You don't really need OMG ZOMBIES to make a good survival game. Survival on its own has thousands of natural enemies, including the fact you have randoms who go KOS Mode.
Also just to add onto the whole, "Lets fuck with people" motif, make wolves hunt in packs, and have their eyes glow at night. Same concept as mountain lions going around and stalking people, but these are pack hunters which for one player, will be an absolute death sentence.
Another thing is I really wish the Rust devs would follow through with the concept art:

Because I totally want an irradiated deer of radiation, and venus fly trap chicken.
thats kind of concept i agree.
but it's quiet stupid ppl complaining about rust and dayz. first time i saw rust i thought about minecraft, stalker and a bit of tomb raider. but implement zombies and everybody thinks about dayz...
rename the rust zombies into goblins, give em wooden clubs or even the rock player uses to gather things. and everybody will talk about a middleage-fantasy-game rip off.
