I hate it when Im moving and a damn zombie spawns right in front of me and turns me into the not-fun-to-be sprinting and jumping zombie. Zombies should spawn in places where players are not close to so people dont get chomp by a zombie that wasnt there a second before.

Agree'd... They dont always bite me but they stop me from running (The entity blocks you) This gives ample time for one of this buddies to sneak up behind you and take a chunk out of your neck.

That is a purely mapping suggestion, so go harp on the mappers if you dislike that. For it all depends on where they place the spawn, sometimes what you are complaining about is done intentionally in order to make the map more difficult and promote the use of teamwork.

Also, zombies don't chomp or bite, they give you a nice cold smack with their hands.

um...who the ever wants to use teamwork? Nobody ever uses teamwork in games, there are always some idiot(s) who dont want to work to win.
Well anyway is stupid how the zombies phase in, zombies are supposed to come out of nowhere but not literally.

Immortal... Sometimes being critical is needed, other times it is not. Zombies BITE people. In every single zombie horror they Bite their victims. I merely said that they would sneak up behind me and take a chunk out of my neck because its more into the zombie feel...

This isn't simply a mapping problem. The way the zombies spawn is that they are spawned from a zombie spawn. Once you get within a certain range, you trigger the zombie to spawn. However, to reduce the stress on half-life, it requires sort of a small area for the zombie spawn to be triggered. The best way to solve this problem would be to make the player step in a trigger and have the zombies that are spawned to immediately follow a pathway to walk to that area, but the developers haven't implemented that yet...

Very Good!! I hope they do that so zombies dont spawn behind me and make me turn into a zombie, then I wont be able to be human fo another 10 minutes because I suck as zombie.

That is why someone worked with someone else and invented teamwork...

They have to come from somewhere - and I think its part of the game's charm. I mean, its a little annoying yeah but it seems similar enough to zombie movie action (running running oh no ran into zombie oh crap the rest caught up im dead braaains). But I think this is one of those things that just has to be as it is (such as dumb marines).
