I understand it's far-fetched, but I think that there should be a slight better drop rate for crowns items. I know, there super rare to get, but I have a friend whose been farming for a couple times for the Mander Palanquin mount from Bellosh, and I went to help her and I got it my first try. Maybe it's luck but it could be cool to see it drop just a little bit better.
There could be a drop rate enhancer like a potion that doubles the rate of crowns drops. But that's just an idea for now.
Best of wishes for those who are farming for crowns drops!!!
