A "hold still while I go kill these guys" option would probably solve 90% of the troubles involved in escort quests. A "go to this point
first, i.e.
around the trap you now-bleeding idiot" directive would solve the other 10%. Putting both on a cooldown would make it non-abusable -- the escortee would see it's a good idea to hold a second or go in a different direction for a little while, but not loiter around until you've xenocided the entire map. Best of all possibly worlds

We know all this already
As for the trap thing, it's mostly just the problems with unavoidable traps that irks me. It's entirely possible for a 100+ damage trap to be sitting in an unavoidable 1-tile wide corridor. That, and that alone, kills probably
75% of the escorts I have die on me.
The other 24% is monster pits. How th'blazes am I supposed to keep that bugger alive when there's 50 ants on the screen and the idiot just slipped past me into the open?
Phase door and time prison -- yes, yes, shut up mage.
The last 1% is stuff like Wrathroot sniping my doods. That's viciously annoying, but rare enough I can forgive, if it's been an otherwise good day.
