Plz stop magical 2M zombie melee swipes kthxbye.
Srsly though - zombies seem to be able to hit me from faaaaaar away. Maybe their ligaments have rotted away and their arms are all stretchy? It seems as though if the slow arm-swipe animation has started, it does not matter how far away I am by the end of it - I'm going to be hit. I find myself shouting "no WAY that was able to hit me" quite a bit. A counter-strike with the spear doesn't hit the zombie that just smacked me? Come ON, you're killing me here. Literally.
Did not do this, that I can recall, in A15-17. The dodge-and-juke melee style was typically pretty effective against a single zed, if they didn't do that you-just-stabbed-me-so-obviously-I'm-going-stumble-towards-you thing. Which is annoying in its own right, but I understand why it's there.
