Diablo 3 hero profiles are now available. A hero profile lets you do a bunch of things via the Diablo 3 community site like check out your character's gear, stats, skills, track your game progress, and share your accomplishments with your friends. Think of it like the World of Warcraft armory, but for D3.
To access your hero profile, just log in to your Battle.net account from any page on the Diablo 3 community site and make sure your Diablo 3 account is the active one. Then click on view profile, and you should be able to access it. Here's my Wizard's hero page.
In the future, Blizzard plans on adding detailed statistics and tabs for achievements and artisans, which would be a great way for people to compare their in-game triumphs with one another, rather than just gear. We'll have to wait and see how soon those implementations will be made though. In the meantime, what do you think of the hero pages? Let us know in the comments section.
