Coupling the fact that once you get a good pistol user around, you can practically clear out an entire horde without even spending an action-the lost are more of a boon than a bane if it was not for cheaty AI (bunch of lost surrounding an advent dude? better run them all to the closest Xcom operative! even if he is concealed and we technically are not supposed to see him. ESPECIALLY if he is concealed and we are not supposed to see him.)
