I have a strong build and damage: the enemies can't kill me even if I just stand there doing nothing and kill everything except villains/elites in 2-shots or less. The issue is that I'm supposed to protect a cogitator, but enemies come from either direction and immediately start shooting at it. Even if I jump to a group, kill it in a few seconds then run back across the room to the next group, I can't protect it. It just dies too quickly. Is there some trick I don't know? I haven't had any issue completing any mission prior to this and I'm lvl 65.
