See title. I've repeatedly run into missions where disarmed psi-baits don't work anymore the way they did in the old game.
I'm currently assaulting a landed Sectoid battleship in early August and turn after turn after turn, half the squad are constantly out of action because the aliens constantly keep rotating targets for psionic panic. It's never the weakest soldier like it used to be, it's always 2-3-4 soldiers in random order. Not only that, but the aliens also seem to prioritize armed soldiers over unarmed ones: more than once, I had everyone drop their weapons and as soon as I confirmed which soldiers on the squad were being targeted, I only armed the rest - which immediately caused the aliens to switch targets to the armed soldiers over the unarmed ones.
It's starting to get really annoying. I don't have Psi Labs yet, don't expect to for at least several more months and I'd preferentially not turn on LOS psi unless I have to.
