MM Hunter Intimidation not working

So I noticed on MM Hunters when you use intimidation without your pet it doesn’t work, I am specced into territorial instincts and have no luck in working. Now if you pull your pet out intimidation works. Last week, it was working, but now this week, it’s broken. Is anyone else having this issue? I also checked my pet’s stable and have the correct pet in the slot. Blizzard fix this
