1. Fix the running through wall business. 2. This spawning is a step in the right direction but clearly broken. You should be able to clear out an area or at least kill a zed and know he's dead... for good. If they respawn it should be 30 minutes later in an area with no players near. 3. The new speed is not my favorite, it would be nice to have varying speeds of zeds, for the varying states of muscular decomposition. All of them being speedsters makes it really difficult when freshly spawning, can't even look in any buildings. 4.Lower awareness (ability to sneak by them). 5.(my favorite) gunshots draw them from further away, like the next town over, and out of the woods. So the ass hole bandits on sniper hill get overrun, or a horde of zombies interrupts a tense PvP stand off from all directions. Of course for this to work, melee hits would need to stop making bullet sounds among other things. 6. The damage is good if speed, wall running, and respawn is fixed, it was dumb when they would hit you 3 times and your not even bleeding. 7. With items 1-6 fixed or improved add more zombies.... lot's more, with higher concentrations obviously in larger cities, but also add higher concentrations the further up north you go, like hordes in the fields south of the NW AF for example, because you generally have more gear and weapons the further away from the coast you get (longer you play). All my opinion of course, nothing more, nothing less.
