in my opinion the no gun start is a great idea! people need to recognise that their main threat is the zeds and act like that also the avoiding zeds mechanics work great i often get away by fleeing into a house, wait till all zeds are inside, leaving the house the opposite door and hiding behind a near wall. i would suggest to increase the zombie threat a bit more (maybe more spawns near bildings like in 1.7.1, near a deer stand i saw on sunday more than 28 zeds it was really difficult to avoid all of them :p) and to remove the pvp for a week or something maybe then people will recognise that it is in most cases better to work together instead of shooting on first sight
