Has anyone else on here got into the Beta/Alpha running at the moment ? If not I am in there and seeing as I haven't seen a non disclosure notice on my email I should be able to mention possible UI changes by the visual elements available on screen.
edit: Just double checked and my email from blizzard clearly has the following in:
'Feel free to share screenshots and video of your adventures and to discuss your experiences publicly. '
