I've managed to do auto on IX with the following setup (all sharded):

GRE (I don't have VHE. I think Navigator would work well here too, but I don't have him sharded)
Assassin Corrupt Rescuer (shock, holy, health)
Warrior Newborn of Light (thorns or explosive)
Golden Pharaoh Dog (invis, energy)

The corrupt rescuer will repeatedly lower enemy power to 0, which usually prevents the GCR's from activating their rez power. The thorns on the newborn work great, but i've experienced more crashes with them on vs the explosive. I didn't really notice a difference in completion times, either.

I haven't lost on autoplay yet, but its not exactly quick. I imagine the weak point here is the GRE. I tried my tailgunner but he fell flat due to not being able to res anyone who dies to minions along the way. I tend to put it on autoplay and then not pay attention to it, so any situation that would need eddie switching or micromanaging doesn't work for me.

If anyone can let me know how other eddies fare with this setup that'd be great
