Necromancer issues

I’m playing my necromancer on playstation 4. I have rathma full set.
But when I summon my minions. They don’t attack always. They just stand there doing nothing. when I’m running through rifts or just regular boundaries…like the set doesn’t work?

Common occurrence for all the “pet builds” unfortunately, including sometimes your own follower. Best option is to throw Command Skeleton to at least get the bones going somewhere. That often attracts monsters enough so the other minions detect them and engage. The best ones, in my experience, are the ones which rely on active initiation such as Witch Doctor’s Zuni fetish.

But, D3 is pretty friendly with the monsters (and your buddies) standing around, waiting to be introduced to destruction.
