It is annoying and even distracting at times. I don't think anything server-side should change, but I do think people should use discretion when giving away locations. If someone is camping, go ahead and save the rest of us some time, but it gets very annoying when its happening every round and personally I always get killed whenever I try to listen to the informant.
Leave the specing how it is.
Shut up about other people's positions unless they're camping.
