Those are some sweet ideas That was kind of my Idea behind the team building system so that the larger structure or area would "recognize" that enough players are present and wanting to work towards the common goal also i like the idea about not spawning items in a "controlled" area so people don't just "farm" the best spawning locations. I think that if enough people are grouped that they should be able to, (with the right resources of course) lock down whole areas of small houses again nothing in the area would spawn giving it that "cleaned out" feeling of people have completely taken all the resources out of the area, with larger areas requiring a substantial amount of people to fortify and hold on to, also though i think giving the players the ability to set "rules" for their building or encampment like only allowing certain people to carry weapons or no one at all to carry that way people can hold onto what they have built and if bandits want to take the town or building they would have to do it from the outside or get a man with weapons privileges on the inside to help or some other way to take what they have again I think this would all play well to the "bandit" V "innocent" feel that is currently present in DayZ and really all zombie survival but this would make it more personal, devising a plan to storm the fortified area becomes a task all in it's own with risks and reward. All the ideas about the hospital gear and things like that are sweet they would work well in this system i think the game could use some stability but only if the people playing want it to, they are not mandated to playing in this way but giving them more ways to survive easier ways and always having somewhere safe to rest, but if you feel like being alone you can do that too. I think the addition of underground bunkers would be nice but making them hard to find and making them hard to fortify too is essential or everyone will just go underground me, i like the sun lol but also you would have to venture out for supplies when food and water runs low unless you have some irrigation from some inland river or creek, which would take time and resources to build and maybe hunting local game with the bow and arrow cross bow or silenced weapon, (but not limited too) in order to get food without alerting any potential treats in the are with some game being dangerous and carcasses in the area could bring more game or zombies.
