Skeletal Cleric Problem / Minion Despawn Issue

I've been running a cleric to help keep my brutes alive for my detonate dead build. However the cleric is never alive until we're standing still and it respawns. So I threw resistances and life in to ensure it wasn't being killed, and now I'm confident the problem is simply the game's allowable minion range.

Running through patches of burning ground make the problem abundantly clear. As all my minion hit the ground, the cleric stops in place to heal as me and the brutes continue moving. The cleric barely gets past the border of my screen then the game decides to despawn it and give it a respawn timer.
Now it's no wonder why the darn thing is never around!
It's not monsters killing it, it's GGG... lol

It's also really annoying when they get stuck in a doorway and then the entire lot desapwn

Plz, GGG. No more minion despawn until really, really far away!!!
Also no more minions getting stuck on door when you can plz
