@The Wanderer Crack. As in not crush. There's a difference. I cracked my skull open before getting rammed into a concrete statue. It cracked yes, but it was hairline and my brain wasn't demolished. I was 8 and bleeding from my skull, but I got staples, I was good. (Running around the hospital dripping blood everywhere, mind you)
In order to kill a zombie, the skull has to be crushed and the brain destroyed. By pulling on a zonbie's hair and ramming it into a brick wall, unless you're extremely strong as in Olympic weightlifting, you'd probably only crack the skull. Injure, yes, but not dead.
If you grabbed somebody head and put it into a brick wall, would you completely crush their skull?
I'm not trying to fight, honestly. I have no problem with anybody, I'm just trying to be logical and fair. We can't make zombies this easy to kill, or what's the point of getting weapons if you can kill them all unarmed like that with ease? It's survival, not L4D slaughter.
Again, just my humble opinion. The GM is the boss when it comes to these things but I'm just stating what I personally know and understand. Trying to help, not argue to death and piss off people xD I hope everybody understands
