Hey David for my hunters I have been using the GS macro [custom] that only spams Beastial Wrath Kill Command, Dire Beast.
Basically it will use Bestial Wrath on cd, and try to use one of the two first if it is off CD then it fires if not it moves to the next, constantly cycling that rotation.

I keep my Crows+[Racials/pots/trinkets] as well asCobra shot on separate buttons.
So the rotation is just spam #2 [GS-Macro] use #1 [cobraShot when over 60+ focus all else is on cd] #3 burn cycle cd

Now due to RNG on xtra dire beast procs not all of your hunters will be at the same focus levels.
But typically when I play based off of my mains focus level they all do about the same dps.

Hopefully that made some kinda CENTS..

I noticed if I just roped all of the moves into one macro I tend to spam the key hard and ultimately end up wasting more focus on Cobra shot than the actual abilities due to cycle time and cool downs.

In WoD i was able to get around this issue by doubling up on commands in the macro.

/cast bestial wrath
/cast bestial wrath
/cast dire beast
/cast dire beast

...
the just one line of
/cast Cobra shot

But it does not seem to help in Legion, as BM dps seems to do best if I POOL energy and wait on other cd's such as KC/DB... Based on my mastery heavy stats of course.
