Feature Idea: Flat rate reset all passives

Just like the title says.

This would be handy for me, but not sure about for others.

Flat rate reset button for all passive points, price obviously depending on amount of points allocated. This would be superior to single point respeccing for those of us wanting to rebuild and try new things often, rather than having to spend a bunch of gold to reroute, especially when using the same nodes with merely a different previous pathing.

Thoughts?
