I see this happen a lot: You as well armed Player see an other well armed Player ... You open fire first, but miss.. he runs around the next Corner you after him and then he's gone.
You all know what I mean. I think we Need like in the former DayZ Mod an time you cannot move etc. for disconect (about 15sec). Because at the momentyou can escape other Players and also Zombies by disconnecting.
