Vixen (DayZ)

I started playing two days ago, and so far it's getting better as i'm used to the controls, and have a ROUGH idea of what i'm supposed to be doing at all. The one bad thing which is really putting me off though, is just random shootings. Playing by oneself can get quite tedious, and I get rather excited when I see another player running around. I know people can be touchy though and everyone would be worried about being shot, but I pull out my flashlight so i'm not an immediate threat ( half the time I don't even have a gun yet anyway ) - and make sure they see me by flashing it on and off so I don't take them by surprise. Every, single, time, though - i'm shot on sight. I've even resorted to turning my back to them so they can suss things out first, but nope, then I just get a bullet in the back. What's the point of even playing a game like this then? If people want to shoot others go play CoD or something, seriously. The only time i'd ever kill another player is if I was DYING and in very desperate need of supplies - but i'd see if we could help each other out first..
