A side note here, with recent nerfs, it's likely that Fervor is likely more dps that Dire Beast. The challenge is setting the macro so it's still focus neutral overall, which should be doable, but variable haste may give some problems.

I'm still leaning towards MM spec instead of BM for macroing due to the clunky nature of FF/Frenzy, and the increased # of cooldowns for BM. (SV can be macroed as well, but it also has clunky issues). It's a bit ironic and humorous that MM is likely the easiest to macro now. (But, if they added a cooldown to FF, or put it on the GCD, we likely could macro BM fine).
