Hi, I just subscribed for the “best in bags” option. I have a legendary in my bags that has not been equipped yet. However, it is not suggested by the “best in bags” option. And yes, I can equip two legendaries.
I would need to see your specific case. Post the export for your character from the addon and let me know what gearing strategy you are using (provide a link if it is a custom one) and then I can see your Best in Bag.
You might need to go into the filters/options and set the number of legendaries to two if the website doesn’t know you can equip two.
