I'd be happy just setting being able to set a defense from my own roster so I can see how the AI plays the teams I set for TW and GAC defense.
It would let me adjust mods and turn order more effectively, and eliminate a lot of the guesswork/math when dealing with percentage versus flat modifiers and order of operations (Shaak Ti gives Rex +35 speed, but Rex also gives himself 4% speed for each 501st ally - which comes first?).
Alternatively, some sort of IN-GAME interface where I can set a team and see how all the leaderships and uniques affect their stats would be acceptable. Doesn't even have to be a playable sandbox - just a glorified calculator that understands the internal math better than my guesswork.
