Whoa, whoa, whoa, a lot of these suggestions are just way too over the top for DayZ, which is supposed to be a hardcore survival game. Scuba diving? Sharks? Underwater pistols? The body of water surrounding Chernarus's south and east coasts is just a wide section of a river so I don't think that would make any sense at all. Same with a lot of suggestions that go against the survival aspect. Jumping out of planes, rappeling down buildings, etc is just pure action game stuff and doesn't fit DayZ. I do like your enthusiasm and brainstorming there though, and some suggestions like duffel bags for carrying stuff and more soviet weaponry are good ideas.
