Additional Right Click on Player Options
I agree, have an option for accepting duels, disabled by default. These should only be available in cities or an arena or something.
I would suggest the same for the inspection idea, but the issue is even having the option in game is a way for people to demand being able to see it. Some raid/group leaders may demand you let them inspect you, and if you deny, they may straight-up deny you. Sure, they can ask you to link stuff now, but you can easily enough fake that, so they may as well not ask in the first place.
