Hannah works well in a daw crew. She can torment herself by copying the guilties cast. Lots of tormented models have casts for her to copy. When tormented her suit ignoring aura extends to five inches (Which is a huge table area off her 50mm base.) with creeping terror, and writhing torment gives her some extra mobility. Similarly her sister also works well for similar reasons in a daw crew.
I personally use hannah as the big threat for my opponent to spend resources trying to kill, while the rest of my crew disrupts the enemies schemes. As the rest of daw's crew and Jack himself tend to put quite a strain on the opponents hand, if you can get manage to get Hannah into a group of enemies and attack a low df one it can even be potentially worth while to stone for the suit, drop some blasts and force a bunch of horrer duels on the damaged models.
