Any Beast Spectre Suggestions for Faruul ascendancy node?

I'm looking to do a minion focused Dominating Blow build for the Faruul ascendancy and was wondering if anyone had suggestions for good Beast spectres. I was already thinking of the ape chieftan for easy charges on my army but am unsure if there are any cool DPS beasts out there that could take advantage of the three random affixes is gets and the general buffs from the auras in my setup.

Thinking along the lines of a beast that has crazy attack speed or an aoe spray like the abyss worms or some sort of cyclone generating bird.
