I'm doing a runthrough on Insanity for the achievement.
Its brutally difficult, but I am not running into the AI problems. My squad's AI has been pretty good up 'til where I am. The only real fusterating part I was at was Purgatory at the Warden, as it felt like the enemies were going to spawn forever (I must have killed 40 guys before dying).
Back from the dead, I'm afraid.
