Or at least I hope it is a bug and not intentional!
Since the patch, we do no longer get the option to preview armor not for our profession. Please, change it back. I do not want to have to log in with different characters just to see how the armor would look like, before I choose to keep it or sell it/salvage.
If this is because people are not to get “fooled” and buy armor they can’t use, believing they can, then the red text telling them the armor is not for their profession should be message enough.
