Pinebox chould be changed with Lady J: instead of swordplay give her an ability that boosts pineboxes
Same with Dita and Shielded on Bravado.
I generally like abilities on masters that boost keywords as it encourages you to play more or less in theme.
Investigators could have On Your Heels on Interrogate but I think a lot of issues with Elite is that Intimidating Authority is not enough of a defensive tool looking at their mediocre stats. This works on a lawyer that is 6SS and can stay back as a support piece, but everything that goes in close gets demolished.
