currently, in game if you mouse over someone you get there name and distance.
however it breaks some mechanics of dayz i think.
if your hiding in a bush and they don't visually see you they can mouse over a bush and know your in it. i can scan the horizon slowly to find you( even though i would have had to use binoc's without tags). you can also get tags on people through walls if your in buildings and close enough.
makes getting the range finder pointless, except it has night vision. and sniping is easy mode when you know the distance and how scopes work.
i feel its more immersive and more scary with no tags. makes bandits job a little harder and allows more stealth without tags.
groups of players also have friendly fire issues making it harder for large groups( they have to know where there team mates are and coordinate more). giving solo players a little more of an edge in some situations.
Not sure how the rest of the community feels about it, whats your thoughts on name tags popping up .
