If you are unaware of what ghosting is, it's when a player logs out then logs in on a different server in order to get a position advantage on somebody they are attacking and then logging back into the original server. I thought I'd post this idea that the 42nd were talking about on their stream whilst being ghosted. They said that as well as there being a reload sound to alert you of people logging in, there should also be a log out sound such as a long yawn. Link to stream: http://www.twitch.tv/sacriel
