The minions are handy for a bowazon (I use faith on my multishot zon. Yes, I said it, I play a multishot zon).
The downside is that they have almost zero AI, and will just simply wander around aimlessley and not pay any mind to where you go, so in that regard they are far more useless than necro skeletons, but they still do serve as meatshields and as distractions.
