In regards to the scout, I agree, it is an excellent way of assessing threats within a system that the trader is going to be travelling through. One issue I've had, however, with my freelance escort character, is that a lot of traders, usually powertraders who don't use escorts very often, begin to complain when I leave their scanner range. Even after I try explaining it to them, they continue their complaint, and several times, I've led them through a 15-20 minute run only to not get paid for inadequate service. The one time I listened to the person I was trading with and flew alongside him, we ran into a few pirates in the next system who promptly blew him up, then focused fire on me. The one issue remaining, as I personally see it, is the potential alienation of new players trying to make their way into a secure position in the server.
