Simply put, this is an interface screen which the player uses to customize a character's profile, which inturn can be globally viewed by other players in the same instance or town.
Such tidbits for the profile could include, and could be made optional by turning them off or on by the player:
1) The character's image, identical to the one used for inventory
2) A 100 word or less personalized paragraph written by the player for her/his character being viewed
3) The various titles your character has earned, and not just the one you've chosen to show
4) The character's birthplace (Tyria/Cantha/etc...and maybe a dropdown to choose your own town/city where you believe your character was born) and actual birthdate
5) Level, profession(s) and possibly the XP earned by the character
6) Perhaps a simple questionaire with dropdown options about the character's favorite things, such as place to adventure, weapon of choice
7) Display your PvP accomplishments, such as tournaments or events W/L, deaths, kills and awards (or rank)
8) Maybe even a Location to show your actual world origin (Player, not character)
To view someone's profile, right click on the character's name
Some benefits:
1) Able to show others the weapon/equipment your character is using/holding for selling purposes, or for any visual aide thought of
2) Allow others to see what you've written about your character and get to 'know' you before they get to know you.
3) Enrich the feel of the RP aspect if that's your thing, or find the right players for your PUG in PvE or PvP based simply on their presentation (which is already heavily weighed on by how you ask for a group, or how you request others to join your group)
An obvious downside:
Obviously, the server loads. Only allowing a single profile up at a time per player could help this, as well as automatically closing the profile after a minute of inactivity by the character ingame.
Any thoughts or additions/subtractions? I was only brainstorming, so feel free to go hogwild
