In the Jabba's Realm expansion to Imperial Assault, the Imperial player can get the Scouted upgrade:
Exhaust this card while a hero with a Bounty token is attacking to reroll 1 defense dice. If you do convert all [complete miss] results to [cancel surge] results.
I don't see how this would be a benefit to substitute the best defense dice roll with an OK one. How can the Imperial Player use this card to their advantage?
