Zekoa vs minion build

Sandarah, my infernalist, uses level 24 skeleton minions (arsonist, sniper and cleric) and a level 25 infernal hound.

- I have a +147% minion life (+271% is the most you could get in the witch and neighbouring area)
- I have +20% physical damage resistance (max is +44%)
- I have shield on the skeletons
- I have an infernal hound with Meat Shield (+50% max life)

I was running Zekoa's map T17 - T15 map + corruption + irradiated (both from tower influence and atlas boss passive, which I think doesn't stack).

The short story is that I spend my time rolling around Zekoa, while my minions spend most of their time dead.
On average once every 3 attacks, he hits my minions, which are all clustered so they get all hit - and they all get 1 shotted. So I wait for my minions to respawn, and within 3 attacks they all get 1 shotted again.

I'm fine if I have to dodge roll the entire fight, because depending on attack he either 1 shots or 2 shots me (I have 7370 "life"), but having to do so with 2-3 second of minion dps and 6 second of "cooldown" because they are all dead isn't exactly a fun (or fair) run.

It's not even a matter of build, because the only thing more than this I could have done is spec fully into minion survivability (which makes for a low damage build which doesn't work well), and even then, I'm not sure they'd actually survive.

Solutions I'd suggest (and I suggest to pick more than one):
- Nerf Zekoa damage on minion
- Improve minion AI so that they spread in Zekoa fight
- Increase arena size (so I can kite him away from minions)
