So I know Fenn is kind of in a weird place being such a high cost, but consider the following.
I'm pretty sure it works, but here it goes.
Leia (to me) is more of a stay in the back and make long bomb shots as are the Alliance Rangers. If Leia is focussed, she's got a minimum range of 3 and will more likely roll a surge...for +3 accuracy, putting her in Ranger territory.
If she uses Battlefield Leadership, that allows another friendly figure to interrupt to perform a shot, so let's give that to an Alliance Ranger (elite if you will).
Alliance Ranger makes the attack and it resolves.
Now, Fenn happens to be 3 spaces away from said Alliance Ranger, giving that figure Assault.
Leia makes her attack.
Other player goes.
Now, Alliance Ranger figure can make 2 attacks, and the other two can make 1 attack.
This basically forces the other player to flee with whatever figure/character you're attacking, as you're likely to kill it, opening up 4 attacks from Rangers on whatever else is around.
Again, with Fenn costing so much this is kind of a shot in the dark, but if Fenn costed 7 points...?
Yay? Nay?
