Agree DDT, the intial few times you go hunting it appears fun, but then you realise its just a chore for no real gain (wandering for ages finally finding stuff, then trying to get it all back to camp), armor from the bones isnt really needed cos there is no PvP/PvE and when there are PvP events noone wants to take part incase they lose the armor lol.
The travelling time and bone weight is the main issue for hunting and getting bones etc back, this with the amount of resting while travelling adds to the issue. I also see comfort, and cooking possible having a negative impact on this experience also depending how its implemented. All in all travelling is a chore period too much resting required.
Other than the proposed zombies im unsure what else they have in mind and how this can be progressed. People need a reason to leave their safe zone and at the moment scavenging is all that provides this and even then you dont have to travel too far to find what you need.
