Ah that makes sense actually... The piles of goo that named summons are creatures casting spells so they were likely targetting him and there was nothing you could do about it. I will take a look at that situation and see if I can fix that.
They should only get in over their head when creatures are targetting them. If they are getting in over their head with nothing targetting them it is a bug but I have yet to see that happen when I use them.
I am telling you Gninja, the Inquis was cowering even though the Named Genie in Forgotten Pools was on me. I think it has something to do with the things he drops on the ground (even though it seems the mercs are immune to the effect from them).
But he was following along behind the Genie doing the cower emote the entire fight. Whether it was affecting his abilities or not I am unsure of. The warlock merc in the group was not cowering however.
