Start showing your work (post these sims so we can constructively discuss things) or stop making blanket assertions with no work.

Considering that at the start of the fight you are getting extra focus from RF and DBx2 that the extra 15 focus is not really a big deal, especially if used when you get your first LnL since you know that the first focus free ES will more than regen that additional cost.
I haven't been using Dire Beast as from the femaledwarf it has a lower DPS yield, and I've read several forums about how there is a delay in attacks, and when the boss moves that also is also a minus in DPS. Fervor is what I'm using right now.
