This was exactly my point when i started the tread. I've been playing for 2 weeks now(never played dayz before), and i got shot twice, and not by skill of the other player, but because of my stupid benevolence :) I was tricked into thinking that there are more roleplay players, and not "shoot on sight" playes. But dont get me wrong, this is awsome, it makes you value ingame friends even more. Other than that, there were not other real dangers for me ingame.
As far as zombies goes, i was killed once by 3 or 4 zombies, that surrounded me. Other than that, i was never under the impression that they pose a real threat for me, and thats just because they really dont. When i suggested hordes and more zombies, i wanted to change that. If there were more zombies, even if they would behave like they do behave now, the core of tge game(zombies) would be much more dangerous, as i think it should be, cause this is postapocaliptic horror survival :)
Now, just incorporate exsisting PVP in the middle of that setting, BOOM, it rocks! (i rocks now, i agree, but then it would rock even more)!
