And there are other fights where adds are too spread and BM pets have 0 mobility outside of Kill Command, it's just retarded looking at them chasing stuff around while the MM hunters are blasting Marked Shots at everything on screen without sacrificing damage on their primary target.
With that said, it's not that BM is a bad spec, compared to other classes it may even be a good spec, but MM is probably the best and most superior raiding spec of all classes in the game right now. For the same reason it's a bit sucky in dungeons, it's godly in raids, so it really makes no sense to take any other hunter spec for high end raiding.
