This is my first time posting here so I hope I do it correct.
As a beastmaster specced hunter I was suggested “Unerring Vision”:
Although its a Marksmanship trait. My character is not level 120 yet, but I do not suppose that’s related to it.
When you look at Best in Bags, it should have 3 specs on top of each other on the left side.
If MM is on top of BM, it will try to chose MM traits. Try putting BM to the #1 spot, it should suggest appropriate traits.
