Unless you got some parsing agenda, your job as a BM hunter is to capitalize on single-target damage when it is needed on Beastlord Darmac. Sure, get Beast Cleave going and save Barrages for when the Pack Beasts spawn if the boss is tanked nearby them, but otherwise don't even bother attempting to "overdo" it by getting your pet across the room to cleave them and shit like that. The effort is hardly ever worth it, and other classes can AoE them effortlessly, sometimes even gaining slight single-target by doing so.
It is also why "average" DPS for this fight is not reliable. I was barely hitting 60k for weeks and weeks. This week I hit 78k because some of the AoE-heavy people went single-target builds.

If your objective is to get high parses anyway, get as many people with high AoE to just.. Not do that. Save Barrages for every Pack Beast pack, sit on Focus Fire/Bestial Wraths if you have to in order to get the sweet AoE going and the damage will look something like above. To be clear, though, that parse was complete whoremode:

And it was only really "acceptable" from the perspective of killing the boss because it's 1) an easy boss for us 2) on farm and 3) others went single-target hardmode to compensate.
