The marked for death is big. I think the only reservation is that the Arcane Barb might make the sentries hit harder, since it has a bigger weapon dmg range.
If you wanna test just try to kill ghom without your pets and Zei's stone and time them to see what's faster.
I'm having some issues deciding xD
