An option to allow users to swap the default profile with their own. So any new alts would automatically use the user selected default profile rather than the normal default profile. Could be a really awesome user friendly option!

Definitely a plus one from me! This would be awesome (even though by now I have configured all my alts manually :P)

Please fix this, It may not be a huge issue, because you can fix that in 3 clicks, but still I'm pretty sure most people don't have a unique profile for every class they play to justify this.
In my case i often use PTR, Beta and many characters in general. so for every new char-server combination i have to go and switch profiles, it's muscle memory by now. and my profile list is littered with empty default class profiles from two different localizations

I tried to do this when I first posted, but I lacked the ability then.. I'll try again this weekend, if you haven't done something yourself by then. :)

Really, 2012? I thought this was posted this year :P
