Is it diff 2 per the basic move? Or would you use the players discipline? If it's the players discipline; I assume if you're targeting multiple people you have to target the hardest to hit?
I am leaning towards just keeping it diff 2.. if it's straight up contested, I don't see unleash being worth using.. but I haven't actually played or ran F&D yet, so I'm interested what those of you more experienced folks think.
