While looking at the items list I kept wondering why demon hunter was the default view, then I hit the chat gem at the bottom of the page and voila... different class view

hitting it again switches the view to a different class.. but the gem doesn't cycle on and off it just stays on ... I wonder if that's a website bug.

on the skill calculator page it cycles on and off and gives you a random build each time so I'm gonna guess it's a website bug.
