Prot Paladin tier set from 11.1 is currently bugged. If you have selected the pvp talent Guardian of the Forgotten Queen selected when the Luck of the Draw 2 set procs it will not provide you a queens or even a kings buff triggering neither form of protection. I know normally talents that proc kings will trigger a queens if talented but this is doing nothing.
After playing around with it more I have realized that a queen will appear on myself if I am targetting myself when the buff procs. Otherwise it still does nothing.
