What if you made it so only people in your free company could spectate? Idk if this was already said, but I know in some cases it could be used to teach people who want to do the fight, how to do it by following their guild-mates through the content. To me this would resolve the whole being looked upon by strangers problem, and turn it into a learning mechanic for teaching new players. Though I doubt that would ever replace actually taking them in and carrying them, so in the end I think it would be sort of superfluous. Cool idea though.
