It isn’t. You are essentially making the build weaker by going for a meme concept.
Pets as support on a non pet build is essentially wasting points.
Issue with relying on it for healing is that you are then stuck with a pet that will die to the faintest of whispers on a build where pet stats are basically non existent and the pet itself is just a 1 pointer.
Personally, it is because Pets don’t really suffer from lack of OA/DA and the CC is only really useful against normal enemies since you can’t petrify bosses and such.
You get better options going for mogdrogen.
