I search a bit but didn't found this suggestion in the forum.
Instead of a battletag, could we have the URL to the battlenet profile?
I mean, when I see Autiwa#2768, I can't do anything with it except a friend request. To me, it seems that we want to see the profile and actual toon way more than do a friend request.
Instead of having to do that by hand, it would be easy to create the URL provided the battle TAG one user gives.
Replace "#" with "-", then add the prefix "http://eu.battle.net/d3/fr/profile/", then add the suffix "/"
You then have:
that directly link the the user profile.
I'm wondering if there's a legal reason not to do it, or simply a lack of general interest (except by me obviously) for this kind of feature.
