So you don't like BM because it uses the pet. Congratulations. Was there something new in your idea, or are you just complaining about it?
The real problem I have with BM is the reliance on the pet to do the majority of the damage. On something like Patchwerk it's completely fine. But on fights like Sarth+3 or even KT where your pet is likely to get insta-gibbed at the drop of a hat you have just become worthless. Losing 20% of my total DPS halfway through a fight is minor compared to losing 50% or more of it. And I am only going to assume (or at least hope) that Ulduar has intense fun fights instead of tank and spanks.
