When characters get the message that they have trouble hearing because of the din of the crowds around them or whatnot, there should be a reminder built into the message - something like "You can 'watch' people who you want to listen to" or "You can 'watch all' and 'address /all' to increase the chances that you'll be heard by people in the room". It breaks my heart when I see new players who don't even know that these commands exist. I actually have a macro that I run when I'm in crowded places that does the "watch all" and "address /all" commands because they are so necessary in this game.
